At umix many uucp connections come in over the Merit computer network, which would be a good network to run f protocol over: mostly error-free, 7 bit, and packet-switched underneath. I think that it won't choke on 256 byte data packets, at least at the speed we're sending them. With HoneyDanber it's quite easy to stick it into f protocol with a flag in the Devices file. What I can't see in 4.3 uucp is how to do the same. Nothing in the L.sys line indicates protocol selection, and everything in cntrl.c in 4.3 makes me think that it tries t if it's TCP, f if it's PAD, and defaults to g. Assuming that it's reasonable to run f protocol on dial-ups, and without modifying cntrl.c too much yet, is there any way to force f protocol on an ACU connection?

In 4.3BSD, the protocol type is directly tied to the caller, so if you want to talk 'f' protocol, you'll have to pretend that the device is a PAD. PAD works exactly the same as DIR (there is no PAD driver), so this may be the solution for you. Note that, unfortunately, you cannot put a chat script in L-devices on a DIR or PAD device, so you'll have to put all the rubbish in L.sys. The 4.3+ version that Rick and I are developing supports the "ACU,f"-style notation of HDB; it also has genuine PAD support; and it lets you put a chat script on any line in L-devices. So we nipped all the bugs in the bud. :-) (This note will immediately draw a reply from Bob Page, who'll want to know why the bloody hell I haven't shipped him a copy of the new UUCP yet. Well, I really did copy it to uunet, I just forgot to tell you about it. :-( Pyramid has been shipping it for six months now.) <csg>
