I checked the PC's on my desk with KERMIT 3.01; it correctly drops
DTR with either the HANGUP command (from keyboard -or- a TAKE file) or
the ALT-H-H sequence.  With the HANGUP command DTR stays down
until the Connect command is again issued; with ALT-H-H DTR returns
to life after a few hundred msec.  In either case KERMIT has correctly
responded to the hang-up order.

(I'm watching an in-line LED monitor, so I can watch DTR bounce.)

I suspect that your modem isn't watching DTR.  Most modems can be configured
to ignroe the modem-control leads; if this is the case you can't put the 
modem on-hook from the PC.
