ZMRX not working with connection to TeraTerm or ZOC on Windows #8

Open riwide opened 2 years ago

riwide commented 2 years ago

I am trying to do zmodem from windows system to ZMRX on CPM3 of ROMWBW. The ZMRX -v sits dormant after a first display of a string on screen. It does not respond to zmodem send from teraterm or zoc on windows 10.

Which PC software is it known to work with ?

Tera Term does not seem to enable auto-recognition of ZMODEM transfers by default. There are a couple of changes you need to make to the default setup file (TERATERM.INI) to those going.

First, you first need to enable "Auto activation of ZMODEM Receive / Send." See https://ttssh2.osdn.jp/manual/4/en/setup/teraterm-trans.html#zmauto. I have this set to:

ZmodemAuto=on

Then, you'll need to tell Tera Term the path to ZMRX on the CP/M side using "Receive command for ZMODEM". See https://ttssh2.osdn.jp/manual/4/en/setup/teraterm-trans.html#zmodemrecv. I'm using this:

ZmodemRcvCommand=a:zmrx

That said, it looks there are issues with sending to CP/M via ZMRX with Tera Term that I'll need to look into. (ZMTX seems to work okay.)

Chiming in here to say that I'm seeing the same thing on Linux with minicom, dterm, and a direct invocation of "sz < /dev/ttyUSB0 > /dev/ttyUSB0"

Receiving files from the CP/M box via ZMTX.COM works fine. Starting ZMRX.COM and trying to initiate a transfer fails. Running strace on the sz process shows that sz is receiving the handshake from CP/M, responds to it, but X seconds later receives the handshake ... ad infinitum.

Hi @christopherkobayashi, could you please tell me what system you are running on, what baud rate you are using, and whether or not you are using hardware flow control? Thanks.

Hello @codesmythe,

This is running on a Z80-MBC2 (both CP/M 2.2 and QP/M 2.7). Serial settings are 115200 8N1, neither hardware nor software flow control.

After following the above configuration instructions for TeraTerm (And adjusting the path, since I have ZMRX.COM installed on a different CP/M slice), I can reliably say that this is almost working correctly under CP/M 3, ZPM3. I'm using an SC131 (Z180 based pocket micro, running the latest RomWBW), connected via FTDI USB on serial A @ 115200/8/n/1/CTS/RTS. The one quirk I've noticed is when the transfer is complete, zmrx doesn't terminate correctly/hangs on the receiving end. I usually have to perform a board reset to escape out of it.

Starting ZMRX.COM and trying to initiate a transfer fails.

Did you find a solution and fix the issue ? How ....
