COMMHEX is a diagnostic program that displays information received by
a serial port in two windows. The one window shows data received by
the serial port in ASCII, and the other window shows the same data in
hexadecimal. Characters that are entered via the keyboard (except
F1, CTL-C and CTL-K) are sent to the serial port and are optionally
displayed.
The only keys that have special functions within COMMHEX are the
function keys F1 through F10, and CTL-C and CTL-K.
Function key F1 is used to create, store or load macro character
strings. Up to nine macros may be created, stored or loaded. When
created or loaded, the macros are activated by pressing F2 through
F10. A delay between transmission of each character of a macro may
be set in the initialization window.
A macro consists of up to 80 characters. It is created one byte at a
time by entering its decimal (0-255) or hexadecimal ($0-$FF)
equivalent. When a macro definition is complete, an ENTER with
nothing preceding it is entered to close the string. The macros may
then be stored to a file for later loading, or they may be used
immediately.
CTL-K is used to clear the ASCII and Hexadecimal windows, as well as
the incoming and outgoing byte counters. CTL-C is used to exit the
program and return to DOS.
Each byte received on the serial port is filtered through three
masks; an AND mask, an OR mask and an exclusive OR mask, in that
order. If the default masks in the initialization window are used,
the incoming byte will remain unchanged.
COMMHEX is a Shareware program, which is an attempt to provide good
software at a low cost. You are free to copy the program for all
your friends, but if you find yourself using it on a regular basis,
we ask that you make an $8 contribution to:
