If it's done in a door or whatever, does the calling proggie need to reset

the port when the called program is finished?  Say I write a little shim

that sits between my BBS and my Mailer.  It prompts the user to download

a textfile or something.  I shell out to P.EXE and it fiddles with the comm

port handle.  When it's done, do I need to reset the port again, or does it

automagically reset itself to the way it was?
