Hi Ruedi,
    I too am hoping to one day run one SCC on an MBX860 board as a 2M WAN
port. My general plan was to run the SCC in HDLC synchronous mode and use
the PPP protocol on top of this.  From my quick investigation I found that
in the LinuxPPc /kernel/drivers/char area there some files synclink.c
(rewrite of serial.c) and n_hdlc.c (rewrite of ppp.c). Together they form a
Linux Device Driver & line disipline for a synchrouous PPP link.
Unfortunately the synclink.c driver is dedicated to a PCI serial card
produced by MicroGate.
   What is needed is a new version of 8xx_io/uart.c that sets up and drives
the SCC as a synchronous serial port. This may then be useable with the sync
PPP line disipline from the above driver.
  I have started playing with it but only when I have some spare time....
and I dont seem to get much of that these days :-(

   Please let me know if you get any info from other people or find out any
other possible solutions....

Hi,

I'd like to use one of the currently unused SCC's as WAN interface.
My ultimate dream is to run PPP or Frame Relay at a speed of
2Mb/s on it.

Is someone out there, who has
1. seen something like this?
2. written some kernel modules which support this functionality?
3. seen links containing related information?
4. ideas on how to do this?

If you were doin' something like that, would you first buy a
WAN Interface
card for the PC? (eg. Sangoma, for tests?)
5. Has someone done tests with such a WAN card?

Thanx for any information,

Ruedi
