Serial Splitter Mobile by Eltima for Windows Mobile 2003/2005 operating systems is a new generation of professional system utilities for mobile devices. This is the software for splitting real serial ports into virtual ones. It can be useful if you need several applications to work with the same serial port on your mobile device 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 split real port. Serial Splitter Mobile can create up to 20 virtual ports for real ports splitting - COM0-COM9, VSP0-VSP9. Moreover, all of the ports are equal! You can specify the access mode for every created port - read-only or read-and-write. In case of read-only ports you won't be able to write anything to the port, only data retrieval is possible. Read-only mode can be useful, for example, just to read the data and record the real port activity. With Serial Splitter Mobile you can connect one application to the other, split real ports into virtual ones. As a result, applications can exchange data. Such solutions can be useful for GPS simulation systems. The essential feature is disabling existing serial ports (for instance, COM1 may be used by other device and isn't free therefore) to spear a slot for virtual one and use it for your needs.
