My serial modem is now away.
So I borrowed PCI modem (HSF) from another computer (RH 8.0 installed and this PCI modem worked pretty fine with RH 8.0 kernel 2.4.20).
Then I plug this PCI modem to my computer (Slackware 9.0 installed, same kernel). It seems not to work with my slackware. I just plug it and find it with `kppp', modem is found but no response and cant be initialized. I have enabled my PnP BIOS, it doesn't help.
And there is a somewhat strange.
# setserial /dev/ttyS0
/dev/ttyS0, UART:16550A, Port:0x03f8, IRQ:4
device Conexant vendor 0x14f1 device 0x2f00
pci bus 0x0000 cardnum 0x0e function 0x00: vendor 0x14f1 device 0x2f00
Interupt: pin A routed to IRQ 5
IO port: 0xe800
Serial port ttyS0 and pcimodem uses different IO ports and different IRQ.
I wonder modem is still found and stated `modem is ready'.
(But no response and can't be initialized)
Moreover after I issue...
# setserial /dev/ttyS0 irq 5 port 0xe800 autoconfig
then modem is not found with `kppp'
I have read many `HOWTO' documents, I didn't find any clue.
Anybody please help me.
