Yep, you can just type (for example) `screen 7 /dev/ttyS1 9600 vt100` and it'll open the connection on screen 7. Also works well in .screenrc: screen 1 /dev/ttyS4 57600 vt100 screen 2 /dev/ttyS5 57600 vt100 screen 3 /dev/ttyS6 57600 vt100 screen 4 /dev/ttyS7 57600 vt100 screen 0 bash - ^ Screen 0 is listed last so that's the one that pops up when I run `screen`. I've known about screen's serial functionality for years, but I did learn about it on this list. PuTTY also support serial communication, FWIW. Unfortunately, I believe this discussion got misdirected from Kraig's original point: he seems to be looking for a utility to bridge two serial ports and sniff the traffic between them. A quick Google indicates that he may be interested in slsnif: http://sourceforge.net/projects/slsnif/ http://linux.die.net/man/1/slsnif (better description) Thanks, Kraig, for the idea; I'm not sure that's ever particularly crossed my mind to even try that. Brings up some fun musings... Jima
