Hi!
I have been deeply discouraged whith internal JVC,ISA,Class 1,Rockwell
Chipset modem.
I'm not so familar with Plug&Play, so I'll try to describe
situation:
1. i486DX
2. I have both WinNT4.0 & FreeBSD 3.3. on it.
3. WinNT has detect with pnpisa my internal modem as on "Rockwell
bases" after some time and drivers where instaled.
To detect my modem under BSD I must do the following:
1. Power on (reset)
2. Start WinNT
3. Open COM port, Initialize modem.
4. Correctly restart without "reset" or "power".
5. Than BSD says:
----------------------
/kernel: Probing for PnP devices:
/kernel: CSN 1 Vendor ID: GVC0303 [0x0303c31e] Serial 0x00000001 Comp ID:
@@@0000 [0x00000000]
/kernel: Probing for devices on the ISA bus
/kernel: sc0 on isa Oct 31 14:30:35 salmon /kernel: sc0:
.....
/kernel: sio0 at 0x3f8-0x3ff irq 4 flags 0x10
/kernel: sio0: type 16550A
/kernel: sio1 at 0x2f8-0x2ff irq 3 flags 0x1 on isa
/kernel: sio1: type 16550A
---------------------------
Modem is on /dev/cuaa1 and works properly.
In other way BSD doesn't recognize my modem as PNP device and can't
configure sio1.
Kernel configuration is:
controller isa0
controller eisa0
options "AUTO_EOI_1" #Hmmm - gives speed on each interrapt!?!
controller pnp0
....
device sio0 at isa? port "IO_COM1" tty flags 0x10 irq 4
device sio1 at isa? port "IO_COM2" tty flags 0x0 irq 3
PS: I've tries to change FLAGS, but nothing happens :(
