- Part of it, obviously, is the software. For instance, I find Co/Session
- (remote control software) version 2 to be painfully slow in dialling, because
- it spends a fair bit of time diddling around before it gets around to sending
- the dial string to the modem.
-
- Another big part of it is how long it takes the modem at the other end to
- answer, how long it takes to go through its answer sequence (for instance,
- before my T2500 died :-(, if you had called it you'd have had to wait through
- a couple of seconds of PEP tones, about a second with of V.32 answer tone, and
- then maybe we'd start to negotiate a 2400 bps connection, and then wait
- another second for error correction negotiation, etc.).
-
- If you're tone dialling, set S11 to 50, which is the minimum time (in
- milliseconds) for a tone to be sustained according to the specs. I've seen
- people set S11 as low as 30 and dial entire numbers in a small fraction of a
- second, but the benefits beyond personal amusement were debatable.
-
- If you're pulse dialling, you're pretty much stuck at 10 pulses per second,
- though some modems support fast pulse dialling at 20 pulses per second.
-
- The actual time that the modem spends dialling, however, usually turns out to
- be a small part of the total pre-connect time.
