[lug] Serial Line Direct Connection

Perhaps an easy question for some of you.  I want to use COM1 as a console, no modem control, speed fixed at 9600, 8N1.

I was able to change the speed with setserial:
[root at redhot log]# setserial -av /dev/ttyS0 
/dev/ttyS0, Line 0, UART: 16550A, Port: 0x03f8, IRQ: 4
        Baud_base: 115200, close_delay: 50, divisor: 0
        closing_wait: 3000, closing_wait2: infinte
        Flags: spd_normal skip_test

[root at redhot /bin]# setserial -v /dev/ttyS0 baud_base 9600

But it still doesn't work for me with a simple terminal emulator and a serial cable connected.  I suspect that it is looking for modem control signals which I will not provide.  What is the best way to tell it this is a direct connection?

I looked at mgetty, but mgetty -s 9600 -r    just hangs forever..

Regards & Thanks,

-Steve
