Turning several rs232 connections into a network using terminal servers?
 

Hi,

I have a few robots that talk using rs232.

Previously, I've been controlling these robots with shell scripts based around echoing and cating to and from /dev/ttyS0. They're now getting networked with the aid of ethernet-rs232 converters! So:

Is there any easy way to echo ASCII characters down an ethernet connection in the bourne shell? If not, can you propose a suitable scripting language to do it, or do I have to write out all the C code?

netcat might be what you are looking for.

Yep, just read the man page. Looks great! Thanks.
