Before going there, have you tried a null modem cable on the serial port of your Rivendell machine, connecting it up to another computer running at 2400 (8N1) to see what minicom vs. Rivendell produces? This is your best best to determine what's actually going on. If you get strange characters from RD when doing this, but minicom works fine, then you may have to delve down to hex mode in minicom (or another terminal emulations program) to see the actual codes that are sent and then try to figure out what protocol/settings are being used by RD -- or, just manually brute-force try the many different settings with minicom on the RD machine and see what they come out as on the far end of the null modem cable until you hit a match. My bet is that Rivendell isn't initializing the port correctly. BTW, you didn't mention the process you used to test minicom, but I'm hoping/guessing you stopped the RD daemons to run minicom on the same computer. If you didn't stop the daemons but were able to successfully open up the port with minicom, I'd really wonder what port RD is actually opening. Serial ports are generally only able to be controlled by one application at a time (the lock file that the first comm program creates usually tells subsequent programs to disallow accessing the same port). (That being said, I have successfully used shell scripts in the past to send commands directly to the serial port while minicom had it open (this was useful to use a cron job to send a timestamp/keepalive and telemetry command to a device while using minicom to log the output), but I was not attempting to read data back out of the serial port back to the CLI.) — Sherrod Munday <smun...@ieee.org> _______________________________________________ Rivendell-dev mailing list Rivendell-dev@lists.rivendellaudio.org http://caspian.paravelsystems.com/mailman/listinfo/rivendell-dev
