COMRESET version 1.0 of 12/3/90
This simple program is used to initialize serial ports on an IBM
PC-compatible computer. It was designed specifically because Microsoft
Windows 3.0 running in 386 Enhanced mode does not fully reset the COM
ports if you use serial communications applications under Windows. Run
COMRESET to reinitialize the ports installed in your machine after you
exit Windows, if you are having trouble with communications applications
that normally work correctly but fail after you run Windows on your
system.
List the numbers of the COM ports you want to reset on the COMRESET
command line. (Generally, you should reset all the ports that are
installed in your system.) Include only the number, and separate each
with a space. COMRESET recognizes only ports COM1 through COM4 and will
exit with an error message (and without doing anything) if you specify a
port that is out of range. If a COM port is specified but does not
actually exist in your system, COMRESET will note it with an error
message, but other existing ports you may have specified will still be
reset.
Example: To reset ports 1, 2 and 4, enter the command:
COMRESET 1 2 4
at the MS-DOS prompt.
COMRESET assumes that the serial ports are at the "standard" addresses
and interrupts for COM1 through COM4:
Device Port IRQ
-------------------------
COM1 03f8h 4
COM2 02f8h 3
COM3 03e8h 4
COM4 02e8h 3
Custom versions of the program to address other ports can be produced
on request.
