MOXA PComm
PComm, a professional serial communication tool for PCs, is a software package that runs under
Windows NT/2000/XP/2003/95/98. PComm provides:
y A powerful serial communication library that simplifies serial programming tasks for most
popular programming languages. The serial communication library is useful for developing
applications for data communications, remote access, data acquisition, and industrial control
under Windows NT/2000/XP/2003/95/98, and is a simpler programming solution compared
to the more complex Windows Win32 COMM API.
y Useful utilities such as diagnostics, monitor, and terminal emulator.
y Illustrative sample programs.
y Comprehensive on-line documentation.
Installing PComm
To install PComm, run \Setup.exe from the Documentation and Software CD. Note that the
PComm diagnostics and monitor utilities are for MOXA boards only. To use these utilities, you
must have a MOXA board and the appropriate Windows (95/98/NT/2000/XP/2003) device driver
installed in your system. See the “Software Installation” chapter for instructions on how to install
the drivers.
After installing PComm, click Start, select Program Files, and then the PComm Lite group to
select from the list of utilities and documents.
PComm Programming Library
The serial communication library helps you develop serial communications programs for any
COM port that complies with the Microsoft Win32 API. This library facilitates the implementation
of multi-process, multi-thread serial communication programs, and greatly reduces the time
required to develop applications.
For a complete description of the library functions and sample programs for Visual C++, Visual
Basic, and Delphi, check the help file and the sample programs in the PComm directory.
Utilities
In this section, we provide brief descriptions of each utility. For more information about these
utilities, read the on-line help from the Documentation and Software CD.
Diagnostics (for MOXA boards only)
This convenient diagnostics program, which only works with MOXA boards and ports, provides
internal and external testing of IRQ, TxD/RxD, UART, CTS/RTS, DTR/DSR, DTR/DCD, etc. The
diagnostics program allows the user to check both the hardware and software functions.
To run the diagnostics program, click Start Æ Program Æ PComm Lite Æ Diagnostic. A typical
test report for a MOXA board is as follows:
