Hello freebsd-mobile,
I see under Win'98 IBM TP config utility that internal modem use
following resources:
I/O 0x3f8-0x3ff
0x4e30-0x4e3f
DMA 7
IRQ 4,10
So as I understand I/O 0x3f8-0x3ff and irq 4 is COM1. But
0x4e30-0x4e3f and irq 10 are modem resources. When I'm trying to
config sio0 and sio1 in my kernel config:
device sio0 at isa? port 0x3f8 irq 4
device sio1 at isa? port 0x2f8 irq 3
I have following at start up:
sio0: configured irq 4 not in bitmap of probed irqs 0
si01: at port 0x2f8-0x2ff irq 3 on isa0
sio1: type 16550A
And when I'm trying to use /dev/cuaa0 as modem on COM1 I have error
message from ppp: 'Failed to open /dev/cuaa0'
That's obvious, because FreeBSD can't see sio0 at boot time. I want
to use internal modem. Is it possible to use multiple ports and irqs
definitions in kernel config? Something like this:
device sio0 at isa? port 0x3f8, 0x4e30 irq 4,10 drq 7
to describe my device precisely? Or here's some other way to make
IBM internal modem work fine?
Best regards,
Alex N. Markelov
