I had this problem (I think I had a slightly different error message though)
and this was the solution I used: log into your provider manually using
something like minicom/telix etc. Watch every string up to the very end.
My provider always ended with:
where this is the gateway's IP. You need to give chat a string that happens
--right before-- the other end starts getting responsive, so I used part of
this last line. It works well.
Alternately, the man page for chat lists:
\n Send a newline or linefeed character.
\d Delay for one second. The program uses sleep(1)
which will delay to a maximum of one second. (not
valid in expect.)
... as special characters for 'transmit' strings.
In other words, instead of
... pppgate login: ppp
... pppgate login: ppp\n\d\d\d\d\d
which _should_ enter the ppp string and then wait one second for each \d.
Use enough \d's to cover the time required, maybe time a Win95 login, I have
not tried this since I can use the first method I listed. (which shouldn't
depend as much on 'peak' hours etc.)
How this helps,
