An alternative is to use ser2net which spawns one or more TCP servers on one a TCP port which will connect you to the serial port with the given serial port settings. This allows you to connect to remote serial ports on a networked machine or just locally using your favorite telnet client. You can also use this with the USB adapters as well. So for example I run 5 TCP server ports with a different "serial port speed" setting for each USB adapter port. 2001:telnet:600:/dev/ttyUSB0:9600 8DATABITS NON 1STOPBIT banner 3001:telnet:600:/dev/ttyUSB1:9600 8DATABITS NON 1STOPBIT banner 2002:telnet:600:/dev/ttyUSB0:19200 8DATABITS NON 1STOPBIT banner 3002:telnet:600:/dev/ttyUSB1:19200 8DATABITS NON 1STOPBIT banner etc. Then I control access to these TCP ports with iptables. For ease on my laptop in dealing with cisco and other networking gear's console ports I set up some symlinks and aliases as follows alias c1='console1 127.0.0.1 2001' alias c2='console2 127.0.0.1 3001' ln -s /usr/bin/telnet /usr/local/bin/console1 ln -s /usr/bin/telnet /usr/local/bin/console2 when I want to open the first console port (USB adapter) I just type "c1" and it shows up as "console1" in the konsole tab title bar. You can obviously get more fancy than this but you get the idea. -----Original Message----- From: tclug-list-bounces at mn-linux.org [mailto:tclug-list-bounces at mn-linux.org] On Behalf Of Mr. MailingLists Sent: Thursday, September 23, 2010 4:28 PM To: tclug-list at mn-linux.org Subject: Re: [tclug-list] RS-232 serial communications Wow I'll second that!
