'PC serial port communication program'
|Hello members, I just put available as freeware a new
PC DOS software (only 1536 bytes) that allows you to
"copy" a file to the communication port COM1, 2, 3, 4
at speeds of 1200, 2400, 4800, 9600, specified at the
command line fashion. It checks RS232 lines as CTS
and DSR, if they are down it just inform the user but
it doesn't stop the file transfer. It is pretty nice
to test microcontroller communication software, or
just to transfer some file, even to print to serial
printers. I doesn't use other RS232 lines than TX
and ground, so a simple two wire cable does the trick.
This was exactly the reason to produce this software,
since the traditional DOS command COPY /B file COM1:
doesn't transfer if DSR or CTS is down, and you need
to set the port speed before issue the copy command.
DOS command line is COPY2COM FILENAME.EXT /PS
where P is the port as A,B,C,D for COM1,2,3,4
and S is the speed as 1,2,4,9 for 1200,2400,4800,9600.
Program: COPY2COM.EXE - size 1536 bytes, feb 09 1999.

Will this work on winNT verison 4.0?
Man... I don't know. I have problems even to make
it works fine under Windows95/98 DOS partition...
that insist in change some port lines from time
to time without any reason. Also, a time dependent
program running in a Windows DOS partition will
always suffer because the Windows timeshare. Up to
now the only way (that I know) to avoid any Windows
interference problems is run the machine in pure
DOS or reboot the machine in DOS only.
If any of you know how to control it make Windows
keep quiet during a Windows DOS partition program
is running ... I would like to know, and would
appreciate so much the help.
