I have developed an application that can communicate with a wireless modem via a COM Port, provide by the PC. It works well with both receiving and sending SMSs.
But recently, I try to further extent my application to allow it to commuicate with a multi port modem via an PCI card that provides 4 COM Ports. My program will only request the modem, which is free to send SMSs while the modem, which is busy, will be avalible until it's task is done.
I try to test my program by sending a continuous of 10 SMSs to a particular of the COM port. But my COM port that is receiving the SMSs will hang there when waiting for the correct response from the modem.
