COM port that complies with the Microsoft Win32 API. It facilitates the implementation of
multi-process and multi-thread serial communication programs and can remarkably reduce
development time.
The library provides a complete set of functions as well as various sample programs for Visual C++,
Visual Basic, and Delphi. To view detailed descriptions of the available functions and sample
programs, go to Start Æ Program Æ PComm Lite and select PComm Lib Help, PComm
Porting Notes, or PComm Programming Guide. You may also refer to the sample programs in the
