If you have only one serial port, it should be /dev/ttyS0, corresponding to theS1 in your yasr.conf; that corresponds to DOS com1. If you have more than one serial port, and you don't know which one your synthesizer is on, but it is hooked up to a serial port and plugged in and turned on, without starting yasr I believe you can do echo this is a test > ttyS0 (note the capital S and the greater than sign) and your doubletalk should repeat that if it is hooked up to that port. If not, try also for /dev/ttyS1. there may be a much more obvious way that I am not thinking of right now. I just tried that on my system with my doubletalk which isn't running a screen-reading program right now and it worked. My only concern would be whether the echo command might cause a hangup or anything if you had a modem on the serial port you tried, but I think it should be ok. If in doubt and using a modem on a serial port, try it while offline.
