Jerry:
There may be more going on than your modem settings. Here
are some basic thoughts that may or may not help.
<> XTs and their 8250 or 16450 UARTs will not allow port
initialization speeds greater than 19,200 bps. That's to say
you can configure for higher speeds (i.e. 38,400) and
Net-Tamer will seem to properly take control of your modem.
However, communication between your computer and your modem
while online with an ISP could be garbled. This would or could
explain the authentication error.
<> You may need to experiment with your modem settings for level
of MNP and whether compression is turned on or off. You might
benefit from giving your ISP a voice call to their help desk
or tech support to ask what level of MNP their modems use and
whether they require that compression be turned on or off by
you when you call in.
<> In order to avoid problems that arise from use of multiple
communication programs where the settings of one may be left
behind when another is started, always start out a Net-Tamer modem
initialization string with "ATZ^M" (don't leave out the "^M"!)
Your modem may need time to clear registers and other settings
as an ATZ is executed. Therefore, you may wish to use
something like ATZ^M~~ATxxxxx where xxxxx represents the
various other settings you'll have to include on your own in
the modem initialization string.
<> You may have a dirty phone line. That's to say there is a lot
of electronic noise introduced because of a number of factors
I will not address here. The higher your connect speed, the
more sensitive your modem shall be to such noise on a phone
line. You may not have noticed the problem with your 2,400 bps
modem whereas it's showing up now with a faster modem. If MNP
and compression are turned on, the modem may be spending so
much time attempting to correct for noise that Net-Tamer can't
get in edgewise to execute its login script. Ergo, you
encounter a timeout from your ISP.
