setserial -a /dev/ttyS0: /dev/ttyS0, Line 0, UART: 16550A, Port: 0x03f8, IRQ: 4 Baud_base: 115200, close_delay: 50, divisor: 0 closing_wait: 3000, closing_wait2: infinte Flags: spd_normal skip_test
setserial -a /dev/ttyS1: /dev/ttyS1, Line 1, UART: 16550A, Port: 0x02f8, IRQ: 3 Baud_base: 115200, close_delay: 50, divisor: 0 closing_wait: 3000, closing_wait2: infinte Flags: spd_normal skip_test
It says this in both 2.2.13pre15 and 2.3.19, before and after the setserial command.
2.3.19 was the first 2.3 kernel I've tried since 2.3.3 or so. (As I said above, I only recently switched kernel series). I can try backing out the serial changes that went in during 2.3.16 if you want, but I've got an assignment due tommorrow, so I won't be able to until then.
