Hi, I have a GSM modem that I would like to use with the Arduino. The modem has an RS232 25 way D type connection and i usually connect it to my PC with a 9 pin Rs232 adapter. Communication is over hyperterminal using AT commands. The plan is to have the Arduino issue these AT commands to the mode…
