Modem answers ERROR after an ATZ request
Posted on 2000-03-10
I am creating an application in C language and I faced with a problem of modem. When I need to init the modem (with "ATZ\r" string) while the application is running, I get an ERROR answer from the modem if it answered BUSY the last time. But, when I launch the application and send the "ATZ\r" the first time, all is well.
I'm a beginner with communications with modem, so the error may be quite simple.
