Help needed to read bits on Iris serial ports

[jon mccormack]

I'm trying to access the serial port of a Personal Iris on a bit level. I
need to be able to poll the receive pin of the port and see if it's a
1 or 0. It would be nice to look at the DTR, RTS, etc. pins as well. 
The information comming in wont be in sync so I can't just read
a whole byte at any specific baud rate. 

Can anybody help on this? Information and/or sample code would be 
much appreciated.

Thanks in Advance,

Jon McCormack.
