Kermit has lots of built-in variables. You can see what they are by
giving the command SHOW VARIABLES. Among them are:
\v(dialcount) = 0
\v(dialnumber) =
\v(dialresult) =
\v(dialstatus) = -1
\v(dialsuffix) =
\v(dialtype) = -1
\v(dialstatus) is the one you're looking for. The values are shown in
Table 5-3 on page 116 of "Using C-Kermit". A value of 24 corresponds to
NO DIALTONE. You can also use the \v(dialresult) variable to retrieve the
actual message from the modem.
So if you want to treat NO DIALTONE as a recoverable error, you can do
something like this (I didn't test it):
.\%n = 5
while > \%n 0 {
set dial retries \%n
dial \m(name)
if success break
if != \v(dialresult) 24 break
decrement \%n \v(dialcount)
}
if < \v(cx_status) 1 stop 1 Call failed: \v(name)
The \v(cx_status) variable is positive if there is an active connection.

Thanks Frank; that's what I needed.
