Greetings -

We recently installed a satellite receiver from NCIT, Inc. (PageSat) to
obtain a newsfeed without taxing t-1 bandwidth.  The receiver basically
spews data at 128Kbps to a single pin on the serial port (receive data).

The receive software has a place to define the port, and uses /dev/ttyx
as an example.

What I'm having difficulty understanding is how to configure the port to
run at full bore (115k or more), no hardware handshaking, etc.

Although I've managed to compile the software and get it to work, I'm
experiencing lots of buffer overrun messages from /kernal.  I've looked
at the man pages for getty and related definition files, but still don't
quite get it...sigh.

J.G.

P.S.  If it matters, the news box is a Pentium 133 with 64 Meg Ram.
UARTS are 16550.

Thanks.
