i read somewhere that the kernel just assumes what is what, i know for a
fact that the kernel incorrectly identifies my modem which i hardcode to
IRQ9 (IRQ2) and it detects the incorrect I/O address as well (forget it
off hand i dont have access to the machine from here). during the 5 hour
process of trying to get 3 com ports working on different irqs and
different I/o addresses i read that. as a result of the misdetection i
have to use setserial manually to reconfigure the serial port on the modem
found it.. in the setserial manpage, if this is incorrect it should be
fixed(?)
[from setserial manpage]
During the normal bootup process, only COM ports 1-4 are initialized,
using the default I/O ports and IRQ values, as listed below.
(...)
The "standard MS-DOS" port associations are given below:
/dev/ttyS0 (COM1), port 0x3f8, irq 4
/dev/ttyS1 (COM2), port 0x2f8, irq 3
/dev/ttyS2 (COM3), port 0x3e8, irq 4
/dev/ttyS3 (COM4), port 0x2e8, irq 3
