Hi All, I am trying to use two GSM modems. One for sending the messages and another one is to receive the messages. I have connected one GSM modem in the Serial port. Another one I have connected to the parallel port using the Parallel to Serial convertor. For testing I have tried to send and receive the sms to the GSM which is connected to the parallel port, but it was not worked. Can any one help me for this ? How can I achieve to use two modems in single system ? Please Urgent.....
