COM/IP COM Port Redirector is software that lets your PC applications automatically use TCP/IP connections instead of modem connections. Your applications "see" what appears to be a modem on a COM port, but no modem hardware is present. Instead of dialing a telephone number, the PC application "dials" a TCP/IP network address. Your modem application can communicate with any TCP/IP endpoint by using AT modem commands to "dial" or "answer" network connections.

On the client computer running COM/IP
1. You add virtual COM ports using the COM/IP Control Panel. Each virtual COM port has its own software modem.
2. Your application uses COM/IP virtual COM ports instead of local physical COM ports. If your application uses Windows modem devices, you can create them on virtual COM ports using the COM/IP modem driver.
3. Your application "dials" and reads/writes data using COM/IP virtual COM ports instead of physical COM ports.
4. The software modem processes AT modem commands, including dial commands like ATDT19207413700504000, which specifies IP address 192.74.137.5 port 4000.
5. The COM/IP Redirector automatically makes a TCP/IP connection to the location indicated in the ATDT command, then begins relaying the virtual COM port data stream.

At the remote location
1. The field unit accepts the TCP/IP connection from the COM/IP redirector and the application gets a CONNECT.
2. The field unit can also initiate TCP/IP connections to the client computer, which appear to your application as RING events on the COM/IP software modem.
3. SSL/TLS encryption can be used to protect the data stream, relying on optional COM/IP support for encryption and certificate presentation/validation.
