I do it like this with pyserial:

import serial

serialPort = serial.Serial(port=1,baudrate=115200,timeout=0,rtscts=0,xonxoff=0)
def sendatcmd(cmd):
    serialPort.write('at'+cmd+'\r')

print 'Loading profile...',
sendatcmd('+npsda=0,2')

Then I listen for an answer...

hmm, multiple errors: there should be no space between the at_command, the other modems weren't responding except one. the pdu convertor was also wrong. I have fix them all now. @c0m4

I don't know if there is an AT module, but you can use pyserial to communicate with a serial port.
