The configuration program requires windows, but it can be done with AT commands. If you use the Windows-based config program, it literally configures itself. Doing it with AT commands alone will require reading the manual :-) > 2. Will it run at 128K (both channels) under an operating system other > than DOS/Windows?

If you get a 16650-based serial card, you can get all 128Kb out of it. If you use stock 16550s, you will definitely be limited to 115Kb. > 4.

It looks like a normal modem to ppp. Even the channel-bonding is done by the TA transparently. > I know next to nothing about ISDN, so any enlightenment is much > appreciated... Hope this helps...
