This program was written in order to assist the programmer / technician to
analyze and setup serial / parallel communications.  It assumes the user
has some basic understanding of data communications.  On online Help menu
provides some basic assistance for better understanding.



System requirements:

   IMB PC or compatible using MS-DOS 3.1 or later.
   A special cable-tap for monitoring active communications.

   Although not required, A PC/AT will have much better performance.


Program features:

   Test Serial ports (COM1, COM2) and Parallel ports (LPT1, LPT2) in
   either an Online-active , Monitor-only, or Data-capture modes.

   Automatic testing and sychronization to the serial port data.

   Ability to initialize the serial / parallel ports.

   DOS shell.

   Online Help.

   Microsoft Mouse support.


Program startup:

   Connect your PC/XT/AT serial / parallel port to the device that
   you wish to monitor using the special cable-tap ( or equivalent )
   and load this program by typing [ PORT.EXE ] at the command line.
 
   When the program has finished loading, you may scroll through the
   selection menu to perform the tests you choose.



Program notes:


   When using the Auto baud rate detection, keep in mind that this is
   an early attempt and it is not perfect.  You may have to run the test
   more than once to get accurate results.

   If you select a port which your computer does not have, the program will
   not detect it. So be sure you select the proper port.

   For registered users, you will receive free of charge the special cable-tap
   and any additional documentation.  Also for a smaller fee, you will receive
   any updates, corrections, and additions to this program.
