Summary: How do I detect a hangup?


  Im currently working on a Bulletin Board system for the amiga, using CSIs
multi-forth. ( Which is a FANTASTIC product). My problem is 
  A> How can I detect when my modem loses a carrier? The SerErr Carrier
    lost NEVER occurs unless I unplug my modem from the computer.
  B> How can I drop the line without using the AT command? I know I can
    shut off the DTR by closing the serial device. But when I do it this was,
    when I try to reopen the serial.device for the next user, the system
    crashes.  Can I shut off DTR without closing the device? And does
    anyone have any suggestions on why reopening the serial device crashes
    the system? This also happens if I exect DBWs vt100, and run my system.

           Thanks in advance for your assistance,
                  Mark Carroll
