The above is how Slackware linux version 4....(the revision prior to the leap to 7.0)
identified the PCMCIA modem I have just purchased. (Description is quite correct. The modem is apparently
the Australian and New Zealand version. Also known as RM56V1, RM56V3  and possibly CM-56
(Please note, before I go any further that I am experimenting here and a complete newbie to linux)

cardctl ident also suggested:

manfid: 0x0105, 0x100a
function: 2 (serial)

Machine that I am playing with is an old Everex Expressnote 586.

[Previously I had managed to get a serial port modem running on com 1.
I struggled with both Minicom and pppsetup  but managed to get minicom to dial in
to my ISP....this actually took a while to get happening ...er um...only bout ten hours! no kidding. See the notes on my first tangle with the Expressnote about how I first managed to get the machine connected to my ISP.]
 

I don't know how to make modems work in linux, let alone undocumented PCMCIA modems in undocumented machines so I thought I would document the process as I figure it out. If I put the machine in the cupboard for 6 months again these notes might come in handy. Read on if you like....I don't know where this goes next....experiment....search....read....test....

Shutdown, restart and check BIOS.

Disable IR port and COM1 to avoid an IRQ conflict.

On reboot I notice:
cardmgr[54]: socket 1: Serial or Modem
cardmgr[54]: executing: 'insmod /lib/modules/2/2/6/pcmcia2.2.6/pcmcia/serial_cs.o'
tty03 at 0x02e8 (irq = 3) is a 16550A
cardmgr[54]: executing: './serial start ttyS3'

This looks very promising to me...I guess I just have to figure out how to get my communication software to work and it should be done. Last time this only took ten hours....OK it is Friday night 11.58pm

minicom -s
change serial device to /dev/ttyS3

The previous two boots appeared to show an IRQ problem...not this time....the readme.txt that comes with the modem suggests that it defaults to COM4....?

Other notes from the manual:

-any v.90 hosts do not yet support autodetect. In such cases, it will be necessary to issue an ATS109=2 command to the modem in order to force a v.90 connection.

I add ATS109=2 to the minicom command string.

Exit

Yes...Minicom sends the commend to the modem.

Now

ATDT 96666666

It dials out....allright

connect 50666

Username prompt
Passwordjjjj

Got stuck here...can't remeber how to access PPP
Telnet into my shell account no problem...minor glitch.
 

OK tried my hack routine
 

Login
CTrl-A and then q
Exit without reset
pppd
failing here

Fiddle around with pppsetup

Try 115kbp
PAP

more /etc/ppp/options

This was it....I basically setup the options file above and resolve.conf as per my previous installation. Browsing my sites through Netscape for Linux 1.22am woohoo
