Re: [hylafax-users] Faxaddmodem with Mainpine IQ Express R3.2

[Samuel Zats <samzats@xxxxxxxxx>]

Is there any additional work I need to do to configure the card? Only added the mainpine-10 prototype file and patched the 3 per the site listed before.


Updated the grub.conf to 32 ports. 

For ttyS0/ttyS1/ttyS3/ttyS4: it will actually probe:
Probing for best speed to talk to modem: 38400 19200 9600 4800 2400 1200
Unable to deduce DTE-DCE speed; check that you are using the
correct device and/or that your modem is setup properly.  If
all else fails, try the -s option to lock the speed.

Otherwise, it directly fails:
Probing for best speed to talk to modem: 
Unable to deduce DTE-DCE speed; check that you are using the
correct device and/or that your modem is setup properly.  If
all else fails, try the -s option to lock the speed.

Looking at the ports...

This is what I initially thought, but it seems there are only two serial ports active. Can you suggest any reason for the problem?

The system identifies the modem under hardware. So it is being recognized at some level.

At terminal:
[root@localhost ~]# setserial -g /dev/ttyS*
/dev/ttyS0, UART: 16550A, Port: 0xe800, IRQ: 209
/dev/ttyS1, UART: 16550A, Port: 0xe400, IRQ: 209
/dev/ttyS2, UART: unknown, Port: 0x03e8, IRQ: 4
/dev/ttyS3, UART: unknown, Port: 0x02e8, IRQ: 3

The Linux kernel serial driver allows you to specify the number of UARTs to auto-detect.  Normally the default is four.  Thus, it's stopping after it finds two on your IQ Express because it already found two others on the mainboard (ttyS0, ttyS1).

So in your /etc/grub.conf file on the "kernel" line at the end put an additional parameter:  8250.nr_uarts=32

Then reboot.  That should do it for you.

Thanks,

Lee.
