[comp.binaries.ibm.pc.d] Program to detect modem on comm port

sichermn@beach.csulb.edu (Jeff Sicherman) (04/02/91)

  Anyone know of Ibm-pc/Msdos programs that will check for the presence
of a modem attached to a serial port an ON. Would return an error level
to affect batch file execution. Purpose is to have autoexec file take
alternate paths when modem is active after hours when machine reboots.
