pppd + winmodem on Del i7500

OK, whatever. I don't have any need to do that on 4.x. Is this so you 
can run 'pppd' at startup? On a laptop?

I'm not sure what/why the article is advising what it does. 

I also haven't read it, since my 'ltmdm' port worked out-of-the-box over 
a year ago as soon as I bolted in an IBM mini-PCI card instead of the 
default 3Com junk...

I have the following in my kernel conf, note I don't specify anything 
(e.g. irqs or orts) for potentially dynamically-attached serial devices:

	# Serial (COM) ports
	device      sio0    at isa? port IO_COM1 flags 0x10 irq 4
	device      sio1
	device      sio2

I seem to recall that this is the way it is so I can use the built-in 
serial, built-in (Win)Modem and a "real" serial-based PC-CARD all at the 
same time if I feel like it without re-configuring.

I get this on boot:

	sio0 at port 0x3f8-0x3ff irq 4 flags 0x10 on isa0
	sio0: type 16550A

About 10 lines before that, I have:

	pci0: <unknown card> (vendor=0x11c1, dev=0x045c) at 11.1 irq 10

Which is the Lucent device being probed by the PCI code (which doesn't 
know anything about it). My installation from ports attaches the device 
later (via the startup script installed in /usr/local/etc/rc.d).

My kldstat looks like this:

	andy at tureg(/usr/local/etc/rc.d,11:50pm)[186]-> kldstat
	Id Refs Address    Size     Name
	 1   14 0xc0100000 3359e8   kernel

	14    1 0xc33fc000 3000     ng_socket.ko


After boot, I get this from pciconf -vl:

	ltmdm0 at pci0:11:1:       class=0x070000 card=0x22058086 chip=0x045c11c1 
rev=0x01 hdr=0x00
    	vendor   = 'Lucent/Agere Systems (Was: AT&T MicroElectronics)'
    	device   = 'LT WinModem'
    	class    = simple comms
    	subclass = UART


Huh. Used to be that '/dev/cuaaN' was the device to use. Now all my 
cuaa* devices are quietly rotting in /dev (since Aug 25th or so), and 
the 'ltmdm.sh' script is setting up /dev/cual0 and friends:

    if [ "${HAVEDEVFS}" = "NO" ]; then
      umask 7
      mknod /dev/cual0  c ${MAJOR} 128 uucp:dialer
      mknod /dev/cuail0 c ${MAJOR} 160 uucp:dialer
      mknod /dev/cuall0 c ${MAJOR} 192 uucp:dialer
      umask 77
      mknod /dev/ttyl0  c ${MAJOR} 0  root:wheel
      mknod /dev/ttyil0 c ${MAJOR} 32 root:wheel
      mknod /dev/ttyll0 c ${MAJOR} 64 root:wheel
    fi

Ho hum. Never noticed that before, must edit my ppp.conf for when I 
travel next...

Anyway, I get this from a working device:


	andy at tureg(/usr/local/etc/rc.d,11:37pm)[183]-> cu -l /dev/cual0
	Connected.
	at
	OK
	ATI0
	LT V.90 Data+Fax Modem Version 6.00

	OK
	~.

	Disconnected.

Hope this helps, should give you some things to check at least. Good 
luck!

Cheers,
