   I am looking for some help with getting a 'C' program to grab
   an outside phone line, dial a modem, and establish 8-bit 
   communication with the modem.  I tried setting up a pipe to 
   "cu", but cu seems to chop off the eighth bit.  I tried directly
   opening the port (/dev/ttyXX) and talking to the modem but that
   caused the uugetty to go haywire (understandably).  If I killed
   the uugetty, a new one would be spawned within seconds.

   The purpose of my program is to call an IBM PC from a Unix box
   via modem and then do some file transfer.  The protocol that I
   must use (the Fidomail standard) is eight-bit only.  I have had
   a good deal of experience using pipes and other i.p.c., but I
   am unexperienced at manipulating I/O ports in the way I have 
   described.  I can find no documentation for the procedure, either.

   I would appreciate any help that anyone might be able to provide.
