I have a trailblazer and a Sun 2/170, and flow control problems.  I have
told the TB to fix its speed at 9600 (it's a T1000), and use CTS/RTS. When
using kermit, characters every once in a while get lost, and when using
uucp, receive throughput is about 120-150 cps (which, of course, is
rediculous).  I have tried this:

#include <stdio.h>
#include <sys/termio.h>

main()

{
  struct termios t;

  ioctl(1,TCGETS,&t);
  t.c_cflag^=CRTSCTS;
  ioctl(1,TCSETS,&t);
}

% a.out > /dev/cua0 [minor dev num>128]

This seems to run ok, but has no appearent effect.

There is nothing I can find in the zs, termio, gettytab, stty(1), or
ttcompat man pages, nor in the SunOS 4.0 installation manual.

Surely there is a way to have uucp & getty use CTS/RTS...

Thanks in advance for any help.
