Multi I/O Port Addresses
Default settings for multi I/O port addresses are shown in the table below.
Port I/O Address IRQ Status
LPT1*
378H 7 ECP + EPP
COM1
3F8H 4
COM2
2F8H 3
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.
