Read full 8-bit character from serial port?

["Ron Kneusel" <oneelkruns@hotmail.com>]

I'm using an Apple IIgs to read/write characters while debugging a
program on my PC.  I can send a full 8-bit character easily enough but
my attempts to read a full 8-bit character have failed so far.  The
high-bit is always set no matter what.

I've tried using IN#2 and the monitor routine at $FD0C.  I've also
tried using the SSC routine at $C205 with the same result.  For output
I'm using PR#2 and $FDED which seems to send a full 8-bit character.

So, any ideas on how to read a full 8-bit character from assembly?

Thanks!

Ron
