I think the original poster mentioned something about reading the 
telecom status registers somewhere in the 0x300's.
Since the 8086 has the interrupt table there, and most of the
other I/O goes through I/O ports, I would assume that the
serial port is accessed through I/O instructions.
Thus, this entire discussion is probably moot anyway.
