Multi I/O Port Addresses

Default settings for multi-I/O port addresses are shown in the table
below.
Port
LPT1*
COM1
COM2
* If default I/O port addresses conflict with other I/O cards (e.g. sound
cards or I/O cards), you must adjust one of the I/O addresses to avoid
address conflict. (You can adjust these I/O addresses from the BIOS.
Note: Some sound cards have a default IRQ setting for IRQ7, which
may conflict with printing functions. If this occurs do not use
sound card functions at the same time you print.
