Virtual Serial Port Driver Mobile 4.0
the author of this app says:
Virtual Serial Ports Driver Mobile is a brand-new generation of an already popular driver for mobile devices released by Eltima more than a year ago.
Now we bring a totally new level of serial emulation for SmartPhones based on the Windows Mobile platform!
VSPD Mobile is capable of creating up to 20 pure virtual serial ports in your mobile system. This results in up to 10 virtual serial port pairs available for testing and integration. Two ports in a pair are connected via a virtual null-modem cable and fully emulate real serial ports that may or may not be present in your device.
You can select any port numbers (between 0 and 9) as a virtual serial port pair as well as decide whether to use a COM or VSP prefix. For example, you can create virtual pair COM5-COM6 (or VSP0-VSP9). In this case all data sent by other applications to virtual serial port COM5 (VSP0) will be received at virtual serial port COM6 (VSP9), and all data sent to virtual serial port COM6 will be received at virtual serial port COM5 (VSP0). This can be seen if you run two terminals connected to both sides of the virtual serial port pair. Everything typed in the first terminal will appear at the second one.
Virtual serial port pairs can be used to transfer files, other data and do anything as if there were additional real serial ports in your smartphone or Pocket PC. With Virtual Serial Ports Driver Mobile you can connect one application to another using a virtual serial port pair. Applications will be able to exchange data. This solution can be used, for example, for GPS simulation software. Since version 4.0, VSPD Mobile fully supports all mobile Windows platforms: for Pocket PCs, for Smartphones, for Embedded devices, etc.
