One of our resident experts will probably set you right on connecting
via windoze; however, I suspect that your comms over-run errors are due
to the processor not getting to the UART receive register often enough
to collect a character before the modem delivers the next character.
If the UART tries to store a received character in its
received-character register and it notices that the last character that
it put there hasn't yet been collected, it will set the over-run error
flag, so that you know that characters are going missing. This is
probably a worse problem in 'doze, where the processor spends much more
time doing 'other' things.
If you are missing characters in this way, then all sorts of things
that require a precise order of characters coming in will fail, such as
logging in. I had problems with this whilst trying to get DR Web Spyder
to run quite a while ago. When it performed its log-in and printed
things on the screen, it was plainly visible that characters were going
missing and logging in never succeeded.
Perhaps you could try setting the com port speed to a slower rate,
meaning that characters will arrive at the port from the modem less
often, giving the processor more time to collect each character. Or
perhaps you could abandon 'doze.... A faster processor (and motherboard)
would probably help, but that may not be feasible for you.
Hope this helps.
