At least in my exchange, you can dial much faster
with the automodem than is given in its manual.
(about 8 times)  I speeded up the dialing in Vidtex 4.0a,
by 4 times, and I have no trouble with the results.
Here are the changes I made.  All values are hex.
$1f3c: $0c -> $03
$1f49: $0c -> $03
$1f70: $04 -> $01
$1f91: $3c -> $0f
$1f9e: $28 -> $0a
$1fa7: $02 -> $01
$1fb0: $10 -> $04
