Does anybody have any idea how to reset the RS232 port by software?  I have
encountered a certain sporadic problem (I have had the same problem working
with several software packages, several modems, and on several different
kinds of machines [PC-DOS, Mac, ST], so I don't think it is a fault of my
particular modem, my ST's port, or either Uniterm or the VT52 desk acc.

The problem is that sometimes (usually I think when I get garbage from the
host I am dialing up to:  such as for instance when I accidently dump the
contents of a binary file to the screen, or when the host does not start out
at the right baud rate, etc.), the RS232 port seems to get frozen.  The actual
problem seems to be that keys I type do not get transmitted to the Modem (you
don't see the little lights flash on the modem).  The modem itself has not
stopped working, nor has the carrier been lost.  The most interesting thing is
that (from Uniterm for instance) the BREAK signal DOES get transmitted to the
modem, even under these conditions;  but the port will not accept anything else.
Does anybody have any idea what this problem is, or how one might correct it
short of resetting the ST (that always works, which is good evidence that it has
nothing to do with the MODEM per se)?
