I have vt-198 installed through the Installer. Same issue. Tried reinstalling 
BSD
subsystem and reinstalling vt100 (svn198) also restarting the phone.. but still 
no
effect.

Similar problem here running on 1.1.1 firmware. After installing BSD subsystem 
2.0
(as an installer.app update) Terminal SVN-198 does delete characters, when the
backspace key is pressed, but cursor goes to the right inserting a space. When 
the
enter key is pressed it executes the command without the deleted characters, so 
it
works, but visual feedback is messed up.

Hey, this seems like an issue with zsh, which probably doesn't see the escape 
characters from the iPhone as well 
as bash. :) 

Make sure you've got the latest terminal and you've got the latest BSD 
subsystem, then you should be able to 
start bash, and you'll notice that all of the escape characters from the 
Terminal are recognized properly. :)

This is not a solution. 
You can try to see what the "top" command will produce , even with bash.
I will save you some time. The output would be:

Error opening terminal: network

It just does not recognize the terminal.

same thing here. I also get an error trying to use pine in my she'll. "your 
terminal of the type "network" is 
missing certain functions needed to run pine"
please someone fix this stuff? Does the device team read these comments?

The multiple issues reported here sound like issues with the shell setup.  Do 
you
have these same issues when you SSH into your iphone?  I don't believe these are
issues just with MobileTerminal, but please let me know if that isn't the case.

Also, please see closed issue #37 for the problem related to the "network" 
terminal.

Hi, guys.
I know what's wrong now.

edit /etc/profile
add these lines.
TERM="vt102"
export TERM

this fixes both backspace key and top issue.

try this:)

it also works with TERM="vt100". maybe by default, this value is "xterm"??

Original comment by withered...@gmail.com on 28 Jan 2008 at 4:33

[GoogleCodeExporter]

ok. Without these lines,
TERM is "network". i think this is the problem. This should be new bsd system's 
issue.
just add "xterm" or "vt100", or some valid term type, then this issue just goes 
aways.

does anyone have a copy of etc/profile? I think I screwed mine up and I dont 
have a
backup.

Terminal.app is already setting up the right TERM=vt100 value in the 
environment, the
problem is that it's not passing the -p option to the login program when 
starting the
shell subprocess.  Without -p (preserve), login will throw away the environment 
and
the TERM value will get lost.  This can be fixed by changing this line in 
SubProcess.m:

    char* login_args[] = { "login", "-f", "root", (char*)0, };

to this:

    char* login_args[] = { "login", "-fp", "root", (char*)0, };

While at it, I would also recommend changing "root" to "mobile" to wean off 
excessive
(ab)use of superuser privileges.  Always being logged in as root is rarely a 
good
idea.  Much better to use "su" whenever needed (once it gets fixed in the BSD 
2.0
package).

You can also just use Installer.app to install BSD subsystem 2.0 termfix by Big 
Boss 
and it works just fine.

Fixed in r207 as described in Comment 12 above.

I upgraded like a food to bsd subsystem 2.1 and now I have the same issue. I 
fixed it
by editing the etc/profile again, but this time, I get
"Name collision between vt52 vt52"
"Name collision between wy50 wy50"
and so on, for all the term types. How do I stop this from happening? I know it 
hsa
something to do with the termcap file, but I don't know how to edit it. HELP!

After upgrade to BSD subsystem 2.1 you can use Installer.app to install 
(reinstall?) BSD subsystem 2.0 termfix by 
Big Boss and it works just fine again.

To resolve name collision through SSH connection (not in MobileTerminal.app) 
open:
/etc/termcap

Search and replace following lines:
vt100|network|vt102|vt100-am|dec vt100 (w/advanced video):\
--> (replace with)
vt100|vt102|vt100-am|dec vt100 (w/advanced video):\

#network|xterm|vs100|xterms|xterm terminal emulator (X Window System):\
#   :tc=xterm-r6:
--> (replace with)
network|xterm|vs100|xterms|xterm terminal emulator (X Window System):\
    :tc=vt100

There is no export TERM needed in etc/profile and backspace will work OK...
