I'm writing a DSZ (IBM Xfer program) like program for the Ami, and have run
into a snag!  I need to gain complete control over the Serial port, even if
it is already open!  I've tried opening it for Exclusive access while another
terminal program is currently running, and the CreatePort fails.  Is there a
way deep in AmigaDos that will enable me to gain total access to the Serial
Port?  The program that I'm attempting to write (depends on the outcome here)
will allow a Terminal program or BBS to call an External program to do any
type of file transfers (Xmodem/Ymodem/Zmodem, etc..).  But, when two programs
are sharing the serial port, the incoming data gets split between the two
programs, which just won't do!  If anyone has any possible answers, let me
know.. Pleeze!

Thanx..
