OF compatible serial PCMCIA cards?

OF compatible serial PCMCIA cards?

[Henry A. Worth]

Does anyone know of any PCMCIA serial I/O cards that
would be compatible with OF for use as the OF and/or
XMON/Linux consoles? This would be for the PB2000.

I ran across a site a with links to PCMCIA cards with
Mac support.  It had a link to www.socketcom.com, which
a local store stocks, but the socketcom site did not
have word-one about Mac support. Their serial cards are
16550 based, any hope that OF would support it or at
least enable the interface so XMON and the kernel
could use the port at boot?

There's also a telnet package in OF, what's that about?
Is it possible to telnet into OF?

Thanks,
Henry

Well, I don't think you'll find what you search. I beleive OF can only
use the zilog SCCs in the Apple ASIC. Any other solution would require a
cardbus card with an OF ROM containing OF methods for the serial port.
And I'm not even sure OF can actually use the cardbus at all.

However, for xmon, you can probably use any PCMCIA serial card, configure
manually the TI bridge setup at boot (may be a bit nasty) and write xmon
support for this serial port (not too difficult).

Paul also hacked a way to tie two modem together with a cross-over cable
that works with the internal modem. I don't remember which command you
have to use on the remote modem but looks at what xmon does in
arch/ppc/xmon/start.c when the modem stuff is enabled.

Well, OF can do already bootp and tftp... maybe they have a full IP stack
with a telnet client/server ?

IMHO Mac support does include a Mac driver sitting in your extensions
folder, so far not really interesting.
you went through OF ?
via:

0> .properties
0> words

after that step I can see on my 3400:

upper	/bandit/ti1130@13,1

ata2	/bandit/ti1130@13
ata3	/bandit/ti1130@13,1
[the ata2/3 alias works good for MacOS booting from my 2.5" pcmcia
enclosure HD; did not try it with Linux, 'cause I did not manage to
mount it from my Linuxbox with the pcmcia-cs ide_cs.o and ide.conf,
and therefore could not install Linux partitions on that HD]

don't know what your input/output defaults are [type 'printenv']
but if I remember correctly you can change it for example with

Actually that's something, but I don't see any sign of even a
generic serial extension. What's the name of the extension?

I don't have the card yet. There's nothing in any of the node
words I've checked that screams out 16650 support, the Mac's
native Zilog serial ports aren't compatible with the PC's
16x50's are they? I though that was a much more sophisticated
UART.
