Communicate with serial port device

Hi

Can any one help me ?
I have connected a HID reader to my serial port. It is working fine through my c++ program. Is it possible to connect one more device to serial port and need to work at time. If yes ,how it is possible?

Thanks in advance.

most modern desktop PCs only have one serial port so if you have an application where you wish to attach multple serial devices the simplest thing is to fit a PCI card with 4 serial ports,. Then, as indicated by rajesh6695, you initialise each port in trun and carry out appropriate IO.
