[ont.uucp] Telebit Protocol support

bdb@becker.UUCP (Bruce Becker) (05/02/89)

This message is a question for Telebit Trailblazer sites:

In high-speed mode the Trailblazer can support several
asynchronous protocols. It has been my understanding that
the correct configuration for modems was to indicate
general protocol support (S111=255) on autoanswer, and to
specify which, if any, protocol was to be used (S111=30
for uucp) when dialling out.

Recent experience shows that it is possible that not all
sites adhere to this convention, but instead use S111=255
for both answer & dialling out, or else S111=30.

Earlier on, I had been using S111=30, but changed over to
the above description. However I have come across some sites
which default to S111=255, which means that no protocol
support ends up being negotiated. In the case of uucp calls,
this results in a quite significant loss of throughput.

I'm soliciting whatever commentary & discussion is warranted
on this topic...

 S111=30 for dialin and dialout should be no problem with uucp
connections; they always get the high-speed mode. People with S111=255
on dialout should be gently told that there's an easy way to vastly
improve their uucp performance; you can also make a point of calling
them instead of vice versa. I wouldn't worry about the performance
loss unless they're tying up a lot of your modem time.
