This is true, but if you have echo turned on by default, or your Dialer file turns it on for Hayes-type modems (ex. Telebit) they will see the modem echo the commands back. Unfortunately, having echo on is useful for debugging, and I have my script set up to "send A, expect A, else send A, expect A" etc trying to make sure the serial port and the modem are at the same baud rate. Does anyone know if "ATS50=255E=0\rATDT0123456789E=1\r" will do the correct thing (ie. turn on echo back on before dialing the telephone number)? Dan -- Daniel A.
