Thanks Richard.

I called BT HomeHighway and they have ten times the demand they were
expecting, and my exchange cannot handle it yet. The person I spoke to
knew nothing about BusinessHighway (using the same technology as HH) or
standard ISDN, so comparisons were not possible. Typical.

There's probably a HOWTO somewhere. I'll have a look.

There seems to have been a glitch around kernel v2.0.30, otherwise it's
built into the kernel. NT5 isn't working here yet.

After my recent mega-upgrade session I seem to have lots of
486/mb/vlb/scsi bits left over, but no cases, or the room to have a 4th
(or 5th) computer. Perhaps I should replace the WinModem in Pav with a
Teles, though it will be running NT4 usually.

Mmm, no compression in OS/2 or Linux, and MS will charge a bunch for LAN
interface stuff. I looked at the Zyxel site recently and seem to
remember something about them doing MNP5 (?).

If that's without compression, that's good. Twice what I get (at 33.6kbs
currently).

So does the Teles card work as a serial port, (115k) or does it do
better than that (like a NIC does)?

I was thinking more about something I read a while ago which IIRC said
that the Ascends are limited to 115kbs, so that even with a 56k modem
and a highly compressable file you still only get 115kbs max. I could be
wrong though, and I don't know anything about Demon's ISDN equipment
limitations.

Only one question this time...
