Is SLIP available on the 68030 workstations, specifically a 3500 ???
If so,
a) has anyone used it
b) where is it documented ???? (is it part of SR10.1 ??)

I think SLIP is supported at SR 10.1 . I'd start with a "man" on "ifconfig" . Beyond that I have little information. Andrew Wescott University of Houston Department of Chemical Engineering

(is it part of SR10.1 ??) Yes it is available in SR 10.1 running on a 3500 and I have used it on a number of 3500's. The only documentation is in the release notes and the man page foor ifconfig. The major problem with it is that Apollo made no provisions for using it with dialup lines. They provide no direct way to use the dialup line (it must be SIO 0, another feature) for users to dialup some of the time and other times use SLIP on the port. When I talked to tech support they assumed that it would always be used by two directly connected machines or at least a leased line with modems that don't have to dial and answer. I wrote a couple of programs to enable SLIP to be used on the line until the modem connection is dropped, at which time SLIP is shutdown and a getty is respawned. It involved a lot of monkeying around with the terminal modes to get them to work with both SLIP and while talking to the Trailblazer. One problem still remains: after using SLIP on a line, the line does not receive/interpret control characters correctly, despite having the line discipline set up correctly. This makes it next to useless for mere mortal users that sometimes want to use backspace or kill. The only way to correct this mode is to reboot the node. I expect Apollo does some real wierdness to the driver when it's put in SLIP mode and this cannot be changed from user mode. It seems to be more than just pushing a different line discipline: why else wouldn't it work on the other serial ports? -- Charles. {sun, amdahl, ucbvax, pyramid, uunet}!unisoft!cander
