I'd try adding the M0 to ATE1Q0, i.e., make it ATE1Q0M0 and don't changed the set dial line otherwise. > or > > set dial "ABORT BUSY ABORT NO\\sCARRIER TIMEOUT 5 \"\" AT OK-AT-OK ATE1Q0 ATM0 OK \\dATDT\\T TIMEOUT 40 CONNECT" > > but all this does is cause the script to hang, although at some point, I did get the speaker to turn off. > > If it cant be done through the chat script, is there some software that would allow me to communicate to the modem directly ( this would be nice to do anyhow ) ? cu -l /dev/cuaa0 (cuaa1, whatever) The exit is ~. (tilde dot). You have to save it with an AT command before exiting....as some modems need a cold reboot, this is probably not your best bet, but it's interesting to see what's in those strings. You can usually save a couple of setups to the modem's NVRAM as Y0 and Y1, which may work in the above AT strings.
