Setting up external modem


Could someone let me know the commands to setup an external modem? I am using Puppy 1.0.7 and can't get the modem wizard to recognise it. I have been gleaning stuff from forums, but don't really know what I am doing and haven't had any success.

I have a Sitecom external serial modem connected to a USB port on my laptop via an FTDI adapter. This all works fine on my Red Hat 9 partition.

In Puppy, if I run cat /proc/pci, I get:

Bus 0, device 8, function 0:
Communication controller: PCI device 11c1:0420 (Lucent
Microelectronics) (rev 0).
IRQ 11.
Master Capable. Latency=64. Min Gnt=252.Max Lat=14.
Non-prefetchable 32 bit memory at 0xefffff00 [0xefffffff].
I/O at 0xff78 [0xff7f].
I/O at 0xfe00 [0xfeff].
I/O at 0x9400 [0x9401].

Since my internal modem is a Winmodem, I am assuming this is my external Sitecom.

According to dmesg, the FTDI adapter connection is ttyUSB0.

But if I then run:

# setserial /dev/ttyUSBo port 0xff78 spd_vhi skip_test auto_irq autoconfig

I get:

'Cannot get serial info: Inappropriate loctl for device'

Is there a different set of commands?

Just to be sure, "/dev/ttyUSBo" is a typo isn't ? You really are typying "/dev/ttyUSB0" (zero at the end), right ?

When you connect your modem at the first time to your system, what are the messages at /var/log/messages ?

Thanks for your reply.

Yes the 'o' is a typo in my message - I had put a zero at the end.

I'll go back into Puppy and check /var/log/messages and get back.

Ok, I tried to dialup and then looked at /var/log/messages, as you suggested. These two lines appear to be relevant. The first was from the boot messages; the second message appeared immediately after I tried to dialup.

Feb 7 15:06:11 (none) user.info kernel: usbserial.c: FTDI FT232BM Compatible converter now attached to ttyUSB0 (or usb/tts/0 for devfs)

Feb 7 15:40:17 (none) daemon.err pppd[3745]: In file /etc/ppp/peers/Tiscali: unrecognized option '/dev/ttyUSB0'

Do they tell you anything?

Thanks

John

Sure. It says your modem was detected as "FTDI FT232BM Compatible". Is this correct ? Them that Lucent does not have anything with it.
Not every usb modem works in linux without the proper driver.
Check your modem at http://www.linux-usb.org/USB-guide/x332.html .

Just a hint. Try /dev/usb/tts/0 as the device for setup your connection.

Just to be clear: we are talking about a old phone line modem, right ? It is a dial-up connection, not a ADSL connection, isn't ?
