AAArrrrrggggghhhhh!

I have an AT&T 6386E/WGS equipt with a IPC-802 multi-port card.
I have SVR3.2.1 and the driver version 3.0 for the card.  The
book for the card says that when you open the ttyhxx device
for the port it will do hardware flow control.  the ttyhxx
device for the same port is for software flow control only.

I open the ttyhxx device O_NDELAY and then after dialing the
modem I unset CLOCAL so that I amd using the modem hardware
lines.  This Activates the DCD sensing capibility just fine
but inorder to get the RTS/CTS behavior I also then have to
set IXON.  This too works fine (after a fassion) but this setting
not only operates the CTS line, it *SENDS XOFF/XON CHARACTERS*

I do not like this.

This driver is *broken*!!!!

Is there a way I can either 1) get a good driver from somewhare,
2) set the XON/XOFF characters to some ilegal value so that no
characters will be generated, or 3) activate the hardware flow
control from another angle to prevent the extra and unwanted
software signals.

(I do know that it is the card driver and not passthrough from
the operator terminal or anything....)
