Serial Programming Library
The serial programming library assists you in developing serial communications programs for any
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 PComm directory.
