You mean this: http://smstools3.kekekasvi.com/ There you read: "This software needs a GSM modem (or mobile phone) with SMS command set according to the european specifications GSM 07.05 (=ETSI TS 300 585) and GSM 03.38 (=ETSI TS 100 900). AT command set is supported." And the links I gave you name some commands for sending and receiving SMS. And if you want to write a script to talk with the modem, then expect is the tool. Do you need concurrency? Many people on a network sending SMS through the same modem? Rodrigo.
