Most dialup modems follow to a large extent the specifications of the Hayes Command Set, a specific programming language originally developed for the Hayes Smartmodem 2400 modem. The modem initialization string consists of a series of commands. It prepares the modem for communications, setting such features as dialing mode (tone or pulse), waits, detection of the busy signal and many other settings. - wikipedia.org

I need to read SMS messages from my old Siemens phone (C35i) via serial port on my PC just to see the code behind the scene of an SMS message. Well, it is a 7-bit default alphabeth. The phone support AT-Command, and The AT-CMD Tester is my hand made utility to test the AT-Command set of the Siemens GSM cellphone and modem.

I am not sure if my AT-CMD Tester - which you can get it here - will works on the other type of modem since I haven’t tested it yet, but it works just fine with the newer Siemens GSM cellphone - the Siemens CX6C.
