I have some problems with my modem, the computer doesn't seem to find it
when i'm running freeBSD. It works with the original OS and is then using COM_2.
The problem is that sio1 (COM_2) is not found at startup. Can somebody help me
find it ?!?
I have an AST Advantage 7302 computer using an IBM mwave communications
adapter with an inbuilt IBM v.34 PnP-modem. I have tried to configure
this for use with freeBSD 3.4 with a method described in the hardware compability
FAQ-section. The changes i made is:
1. following lines in kernel,
...
controller pnp0
...
# Serial (COM) ports
device sio0 at isa? port "IO_COM1" tty irq 4
device sio1 at isa? port "IO_COM2" tty irq 3
device sio2 at isa? disable port "IO_COM3" tty irq 5
device sio3 at isa? disable port "IO_COM4" tty irq 9
...
2. and a line added in /sys/i386/isa/sio.c, at about line 2777.
#if NPNP > 0
static pnpid_t siopnp_ids[] = {
{ 0x5015f435, "MOT1550"},
{ 0x8113b04e, "Supra1381"},
{ 0x9012b04e, "Supra1290"},
{ 0x7121b04e, "SupraExpress 56i Sp"},
{ 0x11007256, "USR0011"},
{ 0x01017256, "USR0101"},
{ 0x30207256, "USR2030"},
{ 0x31307256, "USR3031"},
{ 0x90307256, "USR3090"},
{ 0x0100440e, "Cardinal MVP288IV"},
{ 0x340c3235, "MIR0c34" }, /* added for IBM Mwave communications adapter */
{ 0 }
};
/* message at boot-time when pnp0 was enabled in kernel.
CSN 1 Vendor ID: MIR0c34 [0x340c3235] Serial 0x64010000 Comp ID: @@@0000 [0x00000000]*/
3. and at boot time in userconfig i wrote the following
to make the modem show.
pnp 1 0 enable os irq0 3 drq0 0 port0 0x2f8
The sio's then show's as
> dmesg | grep sio
sio0 at 0x3f8-0x3ff irq 4 on isa
sio0: type 16550A
sio1: configured irq 3 not in bitmap of probed irqs 0
sio1 not found at 0x2f8
>
The PnP-card is also disabled at some occasions.
Thank you kindly for some assistance. Åke.
