I tried to hook up my mouse the other day to the second serial
port (modem is on first) and I could not get it to work.  An

open("/dev/tty1", O_RDONLY) just blocked and if I added NDELAY
it didn't block but all the subsequent reads returned 0 bytes.

I know the mouse is ok (I just boot msdos and it works fine).
The microport docs say tty0 & tty1 ignore the serial control
lines but I thought it might still be a problem.  My serial
card lets me force cts, dtr, and dcd true but this had no effect.

I stty'd the port to cs8 -parenb 1200 -ixoff -ixon raw
but this seemed to have no effect either.

I would really like to use the mouse for a particular application
so if anyone has any suggestions I would be quite receptive.

thanks in advance,
			john
