I had a need for something like this - I modified a serial cable such that it had four connectors: DB9#1 goes to device A DB9#2 goes to device B DB9#3 and DB9#4 goes to a "monitoring" system on COM1 and COM2 #1 TX is connected to #2 RX AND #3 RX #1 RX is connected to #2 TX #2 TX is connected to #1 RX AND #4 RX #2 RX is connected to #1 TX #3 RX is tapped to #1 TX #3 TX is not connected #4 RX is tapped to #2 TX #4 TX is not connected Connect signal ground on each to each and monitor using a terminal emulator - Most terminal emulators have the ability to display rather than interpret control characters and escape sequences. You can see what is passing in both directions on the serial cable without affecting it, while not affecting the data stream. What you do not get is timestamp data. Or you can buy serial line monitors that do all this and more. Hope this helps. > -----Original Message----- > From: redhat-list-admin@redhat.com > [mailto:redhat-list-admin@redhat.com]On Behalf Of Leonard den Ottolander > Sent: Thursday, November 09, 2000 1:04 PM > To: redhat-list@redhat.com > Cc: freebsd-hackers@freebsd.org > Subject: [OT] serial protocol analyzer > > > Hello everybody, > > I was wondering if somebody could point me out a serial protocol > analyzer. > Maybe analyzer is too big a word for what I am looking for (I > could be the > analyzer:) ).
