Hi,
I am running RH 7.0 (kernel 2.2.16-22), (dual boot with Win 98)
and I have installed a US Robotics PCI modem. It is a hardware modem
not a win-modem , and the model is: Performance-Pro 3CP5610A (commonly
called just 5610 I believe). I cannot get it to work under linux and
heard that it can be made to work without making the upgrade to kernel
2.3 or higher.
It works fine under Win 98, in plug and play mode, and every time I
have checked, has been assigned to COM5 (IRQ 5, address 0xd000).
With /sbin/lspci I obtain the information (other PCI devices edited
out):
00:09.0 Serial controller: US Robotics/3Com 56K FaxModem Model 5610
(rev 01) (prog-if 02 [16550])
Subsystem: US Robotics/3Com: Unknown device 00d7
Flags: medium devsel, IRQ 5
I/O ports at d000
Capabilities: <available only to root>
i.e. linux "sees" something, and the IRQ and port address are the same
as for Win98.
I then used seterial to set the parameters of ttyS4 so that:
# setserial -g /dev/ttyS4
/dev/ttyS4, UART: 16550A, Port: 0xd000, IRQ: 5, Flags: Fourport
and then did:
ln /dev/ttyS4 /dev/modem
At this point I expected minicom to dial out on the modem, but I get:
# minicom
minicom: cannot open /dev/modem: Device or resource busy
This is the first time I have messed around with ports and such.
Any one know what I am doing wrong, or, anybody who has the same modem
and has successfully negotiated the problem?
Shaheen.
