If one wanted to add dialup SLIP capability to a network, what is the minimum set of hardware required? You definitely need a modem, Telebit TrailBlazer, for example, but after that ... what? A Cisco router will do the trick, but is there anything less expensive? Basically, I'd like to be able to attach a modem to the phone line, the modem to a piece of hardware, the hardware to the Ethernet, and, with a minimum of configuration, be able to dial into that modem and establish a SLIP connection. Any suggestions would be most appreciated. Thanks, in advance! -David

You just need a PC with an ethernet card, a serial card, this programm and two packet drivers ( one for the ethernet card and another for the SLIP in the serial port ) Jose A.

Any suggestions would be most appreciated. > Thanks, in advance! You've just describe the exact specifications of an existing product available from Telebit known as a "NetBlazer". It consists of a Trailblazer modem and a mid-power router in a single box with an ethernet interface. Once configured it will handle dialing in and establishing a SLIP or PPP connection. My interest in it stems from its ability to automatically bring up line when a IP datagam is received, and subsequently take down the line when idle. (just like the "dialupip" SLIP s/w available) I'm not aware of any other routers which will initiate phone connections automatically, but that doesn't mean that they're not working on it.. /John

I went out and got dialupip version 2.0 and installed it on several machines (sony running news, ibm rt running 4.3, and a sun 3 running 3.5). Then I got a Netblazer from Telebit (prior to my present test-related contract) and two additional modems (I'd already a rack of them for my vax, of these two were trailblazers). Now I can a) slip into my office from my sun 3 at home, b) slip from the telebit test lab over to my office, c) assuming I'd scads of routes at home and at my office, rip with the best of them. Total cost, well let's say I got a very good price. Most of the "cost" was debugging dialupip2.0. If I'd have had to actually pay for what I've gotten, I would have, and that would be my host-independent slip|ppp link to the rest of the world, e.g. a regional or commercial or cooperative carrier. Oh, at least 9.6 over standard voice lines, 19.2 when PacBell is not under too much stress. Sync cards at 56Kb would be in next Christmas' stocking.
