Can I send modem AT commands via generic text printer?
Okay, What I am trying to do is to send AT commands via a generic text printer placed on COM3, to communicate to a modem also on COM3. I am able to hit the "Print test page" and can hear the modem pick up the line, so I know it is using the same com ports and are communicating at least garbage at this point. I have been unsucceful in sending any AT commands via this however. Has anyone ever been able to send AT modem commands via a printer on the same com port?
