[Boost-users] communicate with GSM MODEM

Hi Everyone! I would like to ask if someone knows how to use in detail the serial_port() mechanism. I want to create an API application where I will send SMS messages from the pc instead of the mobile phone/gsm modem. Of course, the mobile phone will be connected to the PC from a com or tty serial port. Despite that, I would also like to receieve the inbox from the mobile device. By other words, I need a way to send AT commands to my gsm device and then after receieve the answer. How can that be made easy? Thanks Evaggelos
