I just got my hands on a 3Com/USRobotics 3CP5610 PCI FaxModem. This is
the very same modem listed on the SxS site (Modems ->USR) as being a
real modem that works under Linux. I've already gone through the steps
suggested on the SxS, and i am still unable to get the modem recognized.
"lspci -v" output for the modem shows the following:
01:0b.0 Serial controller: US Robotics/3Com 56K FaxModem Model 5610 (rev
01) (prog-if 02 [16550])
Subsystem: US Robotics/3Com: Unknown device 00ad
Flags: medium devsel, IRQ 10
I/O ports at dff0 [size=8]
Capabilities: [dc] Power Management version 2
dmesg sees the beast:
ttyS04 at port 0xdff0 (irq = 10) is a 16550A
/proc/interrupts shows:
CPU0
0: 110280 XT-PIC timer
1: 1385 XT-PIC keyboard
2: 0 XT-PIC cascade
3: 0 XT-PIC es1371
8: 1 XT-PIC rtc
10: 826 XT-PIC eth0
12: 12812 XT-PIC PS/2 Mouse
14: 25492 XT-PIC ide0
15: 4 XT-PIC ide1
NMI: 0
ERR: 0
ls -l /dev/ttyS4 shows:
crw------- 1 root tty 4, 68 Jul 13 10:03 /dev/ttyS4
Yes, i realize that there is an IRQ conflict between eth0 & the modem,
however I have no plans to use both the NIC & the modem simultaneously.
Additionally, i brought eth0 down, and unloaded its module and still
have not had any success in querying the modem with the following
command:
setserial /dev/ttyS4 port 0xdff0 ^fourport ^auto_irq skip_test
autoconfig spd_vhi
Whenever I attempt to query /dev/modem (which is symlinked to
/dev/ttyS4) kppp tells me that the modem is busy. I've turned OFF
PnP-OS in the BIOS, and even tried assigning a specific IRQ to the PCI
slot that the modem is using (in the BIOS as well) but no dice. I've
also tried different PCI slots.
I have tried this under both 2.2.18 & 2.4.6 kernels, if that matters.
Usenet is littered with others who have struggled to get this exact
modem working under linux, and many have had success (but not all). So,
i'm just kinda frustrated at this point.
