  Hello,  I am having problems getting my serial port (/dev/tty01) to engage in 
bi-directional communications.  I compiled my kernel with the following line:

device		sio1	at isa? port "IO_COM2" tty irq 3 vector siointr

  ...That's what I used and I cannot get it to work still.  I am absolutely 
100% sure that my modem is on COM2.  Otherwise I wouldn't be leaving you this
message now.  Any possible help would be great.  Thanks ahead of time.

Phil
