Hi Ian, do you think its possible to get serial-port-support for the terminal-output (against the USB-CDC-serial)?

I did try to get it working myself, but failed.

In CMakeLists.txt I changed from pico_enable_stdio_usb(Pico_1140 1) pico_enable_stdio_uart(Pico_1140 0) to pico_enable_stdio_usb(Pico_1140 0) pico_enable_stdio_uart(Pico_1140 1)

In getline.cxx and kl11.cxx i replaced tud_cdc_write_char ==> uart_putc tud_cdc_flush ==> couldnt find the same for serial/uart - maybe stdio_flush tud_cdc_available ==> uart_is_readable tud_cdc_read_char ==> uart_getc

I also did add the configuration/init of the uart to getline.cxx and commented out the wait for SB-conected in Pico_1140.cxx

[EDIT] I did it get working in the 2nd try - was mainly my non-working serial-telnet-server on a ESP8266, now the serial-telnet-server is on a ESP32S2 ;)

But only small thing I which dont like in my part-of-code - I dont know to get the right SCOPE for 2 settings - which I have to include in getline.cxx, kl111.cxx and Pico_1140.cxx:

#include "hardware/uart.h"

#define UART_ID uart0
#define BAUD_RATE 115200

The follwing I only have in the Pico_1140.cxx:

// We are using pins 0 and 1, but see the GPIO function select table in the
// datasheet for information on which other pins can be used.
#define UART_TX_PIN 0
#define UART_RX_PIN 1    // Set up our UART with the required speed.

and this after int main():

    uart_init(UART_ID, BAUD_RATE);
    // Set the TX and RX pins by using the function select on the GPIO
    // Set datasheet for more information on function select
    gpio_set_function(UART_TX_PIN, GPIO_FUNC_UART);
    gpio_set_function(UART_RX_PIN, GPIO_FUNC_UART);

As attachment my changed files: Pico1140_serial.zip

And I got no clue how to wait for the serial connection like you do with USB. I got such a thing for RunCPM in the Arduino-IDE:

// ==========================================================
// Wait for a # keypress to show-up the Startup-Messages
// ==========================================================
 int bootup_press = 0;
 int bootup_byte  = 0;
 int bootup_led   = 0;

  _clrscr();
 //  _puts("Waiting 2 seconds before starting keypress-routine...\r\n");
 // delay(2000); // wait for ROM-Messages and then flush the serial interface
 Serial.flush();
   while (bootup_press == 0)
     {
       if (Serial.available() > 0)
        { bootup_byte = Serial.read();
            if (bootup_byte == 35) // ASCII-Code 35 = #
              { bootup_press = 1;}
        }

        _clrscr();
        _puts("Press the \e[1m#\e[0m key to \e[1mbootup\e[0m RunCPM :)\r\n");

        if (bootup_led == 0) {bootup_led = 1 ; digitalWrite(LEDG, HIGH);}
            else             {bootup_led = 0 ; digitalWrite(LEDG, LOW); }

        delay(250);

     }
   Serial.flush();
   digitalWrite(LEDG, LOW);

// ==========================================================

But dont knwo how to program it in the Pico-SDK:

Kind regards Guido

Isysxp commented 1 year ago

Dear Guido,

Thanks for this. I am afraid that the Pico-SDK serial IO scheme is not great as several changes need to be made to change from SerialUSB to Serial. I would note that I have found the SerialUSB system to be quite reliable. However, I assume you wish to connect the Pico to a 'proper' terminal. I think your code is fine. Normally, you do not need to wait for the Serial line to be active. However, you cannot easily. tell if anything is connected at the other end. For this you will need some extra lines from the Pico to your Serial device ... these are DTR/DCD and possibly RTS/CTS (modem signals). Personally, I wouldn't bother and just make sure the terminal is online before you press reset!!!

Regards, Ian.

Dear Ian,

Normally I also like the easy way to connect to USB ;) But sometimes its interesting to connect the system to another device and then the serial way is the prefered one ;)

Also I had talked to some people and they would connect - as you wrote - a proper terminal like a read DEC Terminal or a serial Bluetooth-Converter :) I also like this serial2Telnet-Thing.

I was surprised that my code did worked so well. Its great to hear that you will find my code "fine" too ;)

Kind Regards, Guido.

guidol70 commented 1 year ago

Dear Ian,

I did it now the following way: I created a set_aurt.h and included this one in all of th 3 files - "problem" solved for me :)

The huy who wants to connect the Pico_1140 serial to a real VT100 did need a 9600 Baud version.

In the first try the version did also use 115200 Baud because the stdio_init_all(); in Pico_1140.cxx seem to stanard-init with 115200 Baud :( (did read that some time anywhere)

So I did after the normal init a full_uart _init stdio_uart_init_full(UART_ID, BAUD_RATE, UART_TX_PIN, UART_RX_PIN); and now the serial port is correctly initialized at 9600 Baud ;) which doesnt seem much slower than the 115200 Baud :)

Kind Regards & a happy new Year 2023, Guido

Isysxp commented 1 year ago

Dear Guido,

Thanks again. I am not surprised about the apparent serial speed. The serial I/O is throttled at 1 transaction per 10000 cpu cycles. You could reduce this (see line 161 in avr11.cxx (500) and kl11.cxx (20)) a bit but other problems may arise. I think the speed is about right and is about 9600 baud or so.

Regards, Ian.

guidol70 commented 1 year ago

Dear Ian,

the serial speed at 9600 Baud seem quite OK for me. With a ESP8266/ESP32-serial2Telnet-Adapter it doenst look so fine like on a VGA32-FabGL-Terminal when connected serial at 9600 Baud - but thats because of the Telnet-packet-size then the output doesnt look so fluid ;)

Kind Regards Guido

Isysxp commented 1 year ago

Please see the latest info in the images directory of the repo. The .UF2 file has been built with both serial and USB support. By default the baud rate is 9600. You can use either or both. NB this build will not wait for a USB connect and the data will stream from the serial port(s) immediately. See line 106 in Pico_1140.cxx to enable/disable a wait for a USB connect. I will close this thread as the serial option is now working.

Dear Ian, many Thanks for this very elegant design for both type of ports! ;) In my mind I have memorys that you mentioned the chance for a type of config-file?

Great to this would be a top-notch for reading a config-file before starting the real Pico_1140 emulation and to set the parameters of Pico_1140.cxx and hw_config.c from from the config-file in a format like this:

UART0TX:0
UART0RX:1
UART1TX:20
UART1RX:21
UART0SPEED:9600
UART1SPEED:9600
WAIT4USB:1

SPIBUS:1
SPIMISO:12
SPIMOSI:15
SPISCK:14
SPISS:9

Do you think thats possible? Thats would be very hepfull for a simple and universal "onthefly" hw-/sw-configuration.

Kind regards Guido

Hi Bruno,

I had forgotten to add this to the repo.

Update the tusb_config.h which is on my system at /home/pi/pico/pico-sdk/src/rp2_common/pico_stdio_usb/include

Change the line

define CFG_TUD_CDC (1)

to

define CFG_TUD_CDC (2)

Copy the attached file to : /home/pi/pico/pico-sdk/src/rp2_common/pico_stdio_usb

I hope you can find the correct paths on your system as I use VSCode in windows. I have had a guess above for the path that might be used under Raspbian..... If you still have a problem, let me know and I will install the PicoSDK under Linux and see what is going on.... When I have enough info about the options for various dev environments, I will update the repo.

Regards, Ian.

Image has support for RL and RK devices, so you can mount one additional DK disk when image is running. One TS tape device is also genned, so you can install software from tapes if image is running in simh, and perhaps for the future tape device when is available in Pico emulation :-) . rsxm32-for-cbl.rl02.zip

Two terminals are defined, so you can log in on the second terminal too. Maybe some cleaning is also needed, but that some later.

Dear Bruno,

Beilliant. This took a bit of detecive work to get it to work. cc test.c .... no problem. The crucial thing is the /CP flag to TKB as in: mcr tkb test/cp=test,lb:[1,1]ceisrsx/lb I haven't managed to find the DCL equivalent of this. This is required for a number of library routines including terminal I/O. Also note use of EIS library for RSX.

Dear Bruno,

Well, that was quick!!! However, it is as expected. You have chosen a build for an FPU rather than EIS. See: [6,1]BP2DEF.DOC This is the output of the initial dialogue. Can you fix this?

Here is BP2 install with EIS, but same result. It must be other problems. Maybe is a problem with intensive disk I-O because BP2 is not installed with resident library, which I can not make while it ask for too big partitions for RMSRES and BP2RES. I am trying for 2 days, but unsuccessfully, 124 KW is the minimum for this. Perhaps an experienced RSX system programmer can do this. rsx11m46-bp2.rl02.zip

Dear Bruno,

This build is working but causes a page fault in the Pico emulation. Leave it with me a this problem seems a bit obscure .... as always!!!!

Dear Bruno,

Sorry for the delay. Your disk image is valid and works OK with Simh. However, I have now found out by a very circuitous route that there is an underlying major fault with the emulation. Put simply, the original code places the general registers in the IOPAGE (which is correct) but, at an arbitrary and unmapped location which does not match the true 11/40 cpu map. This will take a bit of time to sort out as it is a fundamental design flaw. I am amazed it has not been seen before. Anyway, do continue with a combined Fortan/Cobol/Basic build if you can as I am sure I will get this to work.

Regards, Ian.

Thanks again for this. I have now fixed the app and Basic Plus 2 runs fine. I have updated the repo including the .uf2 in images if you wish to use this. Again, this build and the source do not wait for a USB connect so that just the serial ports may be used. I wonder what the next error will be!

Hello Ian!

Thank you very much. I will continue to work on images. Basic now works.

I wonder what the next error will be! :-) No problem, if you really want: Kermit crashes when you are in local mode connected to remote Linux running Kermit in server mode and issuing remote commands. It is not so essential, but that is also one issue. I can transfer files to image with SIMH or with second DK disc. Best wishes, Bruno.

Hmmm. How much RAM you have in your uf2? I have built from Ian's git, and it has 112 KW. Maybe is that issue? Or you're trying with my unsuccessful build with fpu? Please use the last one which I have to upload their rsx11m40-for-cbl.rl02.zip

Strange - I added the latest changes for kl. and kb. from the commits to my source, but only have 96.K MAPPED When and whre are the changes for 112KW? - when not in the KL11.* change/commit?

And in your file rsx11m40-for-cbl.rl02.zip is only a version rsxm32-for-cbl.rl02 Is thats right?

With this rl02 I do get:

>INS LB:[1,54]BP2IC2/TASK=...BP2/INC=1000
INS -- File not found

Sorry, wrong image. There is one more time. rsx11m46-bp2.rl02.zip Ian will answer for the exact commit with the change to 112 KW, I didn't ask, so I don't know.

Found the 112KW change in unibus.* when the RL-handler was updated. ;)

With your new image it does work :)

Dear Bruno,

Re: KERMIT. I have updated the DL0 interface for 8 bit I/O. New .UF2 in repo/images. Does this work?

Hello Ian!

Thank you very much. I will continue to work on images. Basic now works.

I wonder what the next error will be! :-) No problem, if you really want: Kermit crashes when you are in local mode connected to remote Linux running Kermit in server mode and issuing remote commands. It is not so essential, but that is also one issue. I can transfer files to image with SIMH or with second DK disc. Best wishes, Bruno.

No problem. At risk of getting out of sync, here is the new DL11.CXX.

No, it still crashes, but it's interesting that sending from Pico to Linux works without problems, but the reverse direction generates "memory protect violation". I will try to somehow install kermit on the RT image and see if the problem is the same there. But it may take some time. I need to remember how RT works with disks and see how to transfer the kermit binary from DECUS tape to an RT disk.

Isysxp commented 1 year ago

Dear Bruno,

If you mean RT11,:I have just had a go at this with (I think) the Columbia build … KRTMIN.SAV under the SJ monitor. It say that I am short of memory. I will check again using Simh to see if there is another problem.

Same case in SIMH RT-11 FB monitor. I don't know, I will be trying later. It is time for a cup of Coffee.

Isysxp commented 1 year ago

Hi Bruno,

Much coffee required! Anyway, Used Kermit under Rasbian to connect to the Pico booted with the RT11XM monitor. Via a connect from Rasbian, I activated the Pico Kermit with VRUN KRTMIN and then put it in server mode. Returned to the Rasbian end, disconnected and then tried RDIR ., SEND and GET and everthing worked!!! It appears that the RT11 version I have cannot use the DL11 ... only the console. In regard of the RSX11M version on the Pico, don't forget that there is a terminal listener on the DL11 interface (ie you can login etc) I wonder if you need to stop this before using the DL11 from Kermit?????

I don't know. However, i can send file from Pico to my Linux with c-kermit in server mode. It crashes when I run remote commands from Pico. And what is more weird, I use SecureCRT which have built-in kermit support and can send files to Pico kermit in server mode. Combining these two methods, a can send files to both direction. I don't know how separate point of failure. rsx11m46-ccc.rl02.zip

Here is my rsx11 image, on which is kermit installed and from which I tested if you wish to test. To run kermit it is task installed as KER.

Isysxp commented 1 year ago

Dear Bruno,

I have been looking at Kermit. The whole area of file transfer is a bit involved as you know. To get to the point, I used Teraterm to send/receive files and it works fine. (Not sure about binaries). ... Pico in server mode ... However, modern versions of Kermit are still a problem and can cause a memory fault. This seem to happen if the Pico is in master mode and the other Kermits in server mode. In this case, a simple remote dir command causes a crash even after very few characters have been sent. (or a get ) I do not know if this might be a problem with the DL11, a protocol error or an emulation error. I have just managed to connect RSX11 under simh to a kermit (RSX11 is server). And, it crashed on send file to RSX11. ...KER disappears from the task map. As I have to use the console for kermit, I can't see the error message but I suspect it is due to a memory fault. Increasing the simh memory to 256K does not help. Therefore, I wonder if this is a protocol error such that the modern kermits are not backwards compatible. It looks like SecureCRT/Teraterm are the only option at the moment. As simh crashes as well, I don't think this can be resolved.

Regards, Ian.

Dear Bruno,

Sorry for another post. Apparently, this is a known problem ... should have looked harder: Importing files to simh RSX? (narkive.com)https://alt.sys.pdp11.narkive.com/0UyJNmJ6/importing-files-to-simh-rsx The trick is to enter 'set attributes off' on the newer versions of Kermit eg K95 etc. This partly solves the problem as the transfer is not always reliable but the RSX kermit does not crash anymore in either direction. I am not really sure if this is a usable option as the transfer is sooooo slow! Probably need another method.......

Regards, Ian.

I don't know. However, i can send file from Pico to my Linux with c-kermit in server mode. It crashes when I run remote commands from Pico. And what is more weird, I use SecureCRT which have built-in kermit support and can send files to Pico kermit in server mode. Combining these two methods, a can send files to both direction.

Hallo Ian, Perfect, all works now. I read that article a few days ago, and I'm surprised that I didn't come across that part where it was mentioned. I should have read more carefully. Thank you again, you made my day.

Dear Bruno,

Thanks for your note. I have to admit to not being too impressed with the Kermit apps for windows/linux> I cannot get binary files to transfer. However, binary send/receive from Teraterm works absolutely fine and the sent/received files match up correctly. I assume it must use a very basic kermit protocol. I am just in the process of trying to speed up the transfers a bit but I doubt if it is possible to get much faster than the 200 bytes/sec at the moment. Will, let you know.

Regards, Ian.
