you may have missed that clogin actually doesnt work for him per-se.  term
length 0 on the box he has does not work, so it skips that altogether and
the pager will appear in the longer command output.  but ...

you may be onto something there, but i doubt it'd amount to much.  it
just affects sends, which is limited and the timeout is on reads.  his
box may just be slow.

I do not recall why -h was used more heavily in flogin.

do not remove the --'s, that has nothing to do with -h.

would you rework that to only send term length 0 if skip-page fails?
