Actually, it doesn't run at any serial speed since there is no serial interface at all. It interfaces directly to the ISA bus and provides a register set that only looks like a UART. > 2) There is another block of 2x3 > jumpers near the center of the board, slightly > closer to the external connectors.

For a typical S0 bus configuration, device termination should be OFF (infinite impedance, sometimes idiotically mislabeled as 0 ohms), i.e. the jumpers should be off. > 3) How do I set up this modem to do 128kb > connections? It's not a modem, it's a terminal adapter. I'm under the impression that the configuration for multi-link PPP is described in the manual. Otherwise it can be gleaned from the online help. I'd have to look it up as well, and you can really do that yourself. Other channel bundling schemes besides multi-link PPP are not supported. -- Christian "naddy" Weisgerber naddy@mips.rhein-neckar.de 100+ SF Book Reviews: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
