CDTEST = Carrier Detect TEST program.
= = ====
Usage: (batch file)
run your favorite dialer program
CDTEST
IF ERRORLEVEL 1 GOTO NOCD
ECHO Carrier Detected !
GOTO EXIT
:NOCD
ECHO NO Carrier Detected !
:EXIT
I wrote this to use with the PD programs AT.COM & DTR.COM
(courtesy of Donavon Kuhn & Jon Niedfeldt) to dial modem,
then start a special mainframe-specific (Burroughs) batch
file transfer system. The assembler code if fully documented
and should be easy to modify (you might want to increase or
decrease the timing loop for your specific application).
I am placing this code in the public domain in the hopes it
will be of benefit to someone else in production use or
simply as a learning tool (as it was for me).
