Terminal

merry · Jun 11, 2003, 01:50 PM

I am trying to use XTerm to connect to a remote machine over a serial line. The remote machine is already configured to accept commands from an alphanumeric terminal.

But I can't seem to find the appropriate documentation/HOWTO

Any suggestions are welcome

What kind of remote terminal service will you be using? SSH, Telnet?

Thats about telnetting into a modem, but the same principle applies to any device.

Thanks. I'm sorry that my original post was so confuse, I'll try to rephrase.

The remote machine isn't a computer, but a device that takes commands (ASCII strings and a couple of extended ASCII characters) from an alphanumeric terminal connected over RS232 (without any modem). I am trying to substitute this "dumb" terminal with a PC - I managed to figure up how to setup the port in Linux, and send some commands with echo - it works, but I can't read the "answers" from the command line. It works from Windows (with Hyperterminal), even interactively.

I was trying to do the same thing from Linux, using XTerm (with escapes for the extended ASCII), but I'm far too noob for that. I can't find a way to connect XTerm throuh RS232 to another machine (and emulate a dumb terminal), except for some cryptic - to me - indications in the Text-Terminal-HOWTO (which seems to deal more with "dumb" terminal operation of a Linux system than Linux terminal emulation for a "dumb" system).

My purpose is to find a way to control that machine while keeping the ability to do other things with the Linux PC. I am trying to use XTerm - but anything else would do, even a combination of "pipes", echo, less etc. (Linux pipes are more complicated than DOS ones and I'm not comfortable with them... yet

). I think it's pretty much like - say - connecting a laptop to a keyboardless server through a serial line (but not by "networking", no ip like with telnet - suppose the server is alredy configured to accept a console on serial and you have to do some maintenance/rescue).

Thanks again

I thought the link I gave explained how to do exactly that with a modem over a RS232 cable. The modem could be any device really, such as a router for example. Basically, telnet is what you need instead of xterm
