What exactly do you need to do?  Are you just toggling DTR on the port or are
you going to communicate through the port?  Most communication software
packages have some kind of hang up command that drops DTR and when you connect
turns it back on.  Yterm will do this with dropcom or the new one 2.1 will
toggle DTR with ^F1, Kermit will do this with ha, Procomm with Alt H.  Not
real sure what you are looking for.
