The computer logically assigns LPTx and COMx names to:
Parallel ports in the address order 378h and 278h
Serial ports in the address order 3F8h, 2F8h, 3E8h, and
2E8h
This occurs during each boot process. For example, when the serial
port is disabled that is assigned to 3F8h as COM1, during the next
boot cycle the computer reassigns the name COM1 to the next
enabled serial port in the sequence.
