Hello,
According to helpviewer you can use special characters for an initialization
string that “modem” will use internally before sending to the hardware
modem. Ex. ^ - drop DTR for 1 second. In other words the “modem” utility
takes the character and translates it into a command for the modem. I would
like to know what modem translate the “^” into so that I can use it in my
application. I’ve looked at the AT command set and didn’t see anything that
drops the DTR line.
Thanks,
Eric

‘^’ = drop the DTR line, it doesn’t translate to a modem AT command, but
rather an action on the serial port itself (ie. taking down the DTR line).
The AT command varies for modems, but some respond to AT&D2 to drop the DTR
line for Hayes compatible.
