'RS232' is an actual working RS-232 Bus Analyzer. A 'Bus Analyzer' program
is simply a program that captures an RS-232 communication between two
devices (i.e. computer and modem). This is extremely useful when trying to
debug any RS-232 protocol problems. This is the type of program that if you
are not sure what it does, you probably don't need it; but if you do need it
and realize you need it, you absolutely have to have it and can't get along
without it.
The file 'RS232.DOC' describes how to use the RS232 program and the supplied
utilities.
The RS232 program will use all existing conventional RAM for the read buffer,
up to 500,000+ bytes on a 640K PC.
The RS232 program has been highly optimized in assembly language for the
best possible performance, enabling capture at 19,200 baud on an 8088 XT
and 57,600 baud on an AT or higher PC.
The RS232 program has the ability to search for specific ASCII or Hex data
and can also write the read buffer to disk for viewing at a later date.
The program monitors and displays both ASCII and hex simultaneously as the
data comes across the line, in both directions, all in real time. The program
also displays whether any parity or framing errors have occurred and monitors
the status of all hardware handshaking lines if so desired.
If there are any features that are missing that you would like, please write
or call and I will certainly consider putting them in the next release.
If you use the programs and find that they greatly speed up your RS-232
debugging, the meager registration fee of $20 would be greatly appreciated.
If you do register, you will be given printed documentation and a free
upgrade when the next release is complete.
To print this file, the documentation, and the order form :
PRINT READ.ME
PRINT RS232.DOC
PRINT ORDER.FRM
NOTE : If you have any problems with 'Overrun Error', see section 3.5 in
RS232.DOC concerning SMARTDRV and other potential problems. I recommend
not using SMARTDRV with this program. I also recommend not running this
program under Windows, it should be run from the DOS command line.
Thank you for your interest in the RS-232 Bus Analyzer.
