COMM-DRV/CE is a serial communication library for Windows/CE and Pocket PC with support for ZModem, YModem, and XModem file transfer and modem communication.

Perhaps best of all, COMM-DRV/CE doesn't require you to have a Pocket PC to develop serial communication applications. Using eMbedded Visual C++ 3.0, with a Pocket PC emulator included, the software behaves identically to any of the Pocket PCs on the market today.
In addition, the DLLs necessary to support both the emulator and actual Pocket PC devices are included. COMM-DRV/CE also features robust hardware and software handshaking for flow control (DTR/DSR, RTS/CTS, XON/XOFF), adjustable communication buffers of any size and support for Hayes compatible modems and all single or multiport cards made for Pocket PC & Windows/CE devices.
Other major features include support for all baud rates in excess of 460K baud, complete source code, and on-line help. Plus, it targets devices based on Windows CE 2.11 and Windows CE 3.0, and is compatible with Pocket PC 2002, Pocket PC 2003, Pocket PC 2003 2nd Edition, Smartphone 2002, Smartphone 2003, and Smartphone 2003 2nd Edition.
