VSPD Mobile creates up to 20 pure virtual serial ports in your mobile system, this results in up to 10 virtual serial ports pairs available for testing and integration. Two ports in a pair are connected via a virtual null-modem pair and fully emulate real serial ports that may or may not be present in your device.

Serial Splitter Mobile is an application, which allows you to split real serial ports into virtual ones in your favorite Smartphone, Pocket PC or other mobile embedded device. It can be useful if you need several applications to work with the same serial port simultaneously. Finally, one program works with one virtual port, the other one with another port and so on, but in fact all of them work with the same splitted serial port. It is achieved by creating virtual serial ports, which are the same copies of real ones. Each application will think that it is working with serial port in exclusive mode.
