Memory Resident Drop-Dtr is a program that does just that, drops DTR by hotkey.

To install Drop-Dtr in memory, just run it with the command line parameter
for comport [1-4]. To use it, hit Alt-Right Shift and a message should appear
on your screen to tell you that it has been executed. This is a fairly well-
mannered TSR, which occupies only 4 vectors, but to help insure its consistent
reliability, it may be best to run it as the LAST TSR loaded.

The second program included is DROP-MOD, this is just an extra program which
will modify the 2 vectors that DROP-DTR uses to maintain the comport, this is
especially helpful if you change the ports you operate your modem on. It can
be run with or without parameters, when run with the comport designator, it
will change DROP-DTR to function on that comport, otherwise it will tell you
what comport DROP-DTR is already on.

If you have any problems/questions/comments please direct them to me on
