Greetings:

I'm using a (56k) dial-up connection for internet, and my phone lines are
often quite 'noisy', causing DUN to often connect at a rather slow speed
(e.g. 14.4, 28.8). If I hang up and redial I can usually eventually get a
'decent' speed (48k+). Sometimes it takes several tries.

Is there a way to configure DUN to automatically disconnect and redial
until it connects at a minimum specified speed?

Keep in mind that the "speed" displayed is initial connect speed and that
may change in the course of the transmission. Many high quality modems are
good at "falling foward", increasing speed when the quality of the
connection warrants it and "falling back", decreasing during periods of a
poor connection. Sometimes in rural areas and/or noisy lines it can
actually increase "throughput"(similar to average speed) to limit initial
connect speed so that the fall forward and fall back features don't waste
too much bandwith on their negotiations. One can set limits by adding the
appropriate "AT" commands to the modem initialization string in DUN.
Certainly one can set it so that the modem will retry if the connection
is not of at least a certain floor speed. The manual for your modem will
explain the AT command set it can use.

Hope this helps.
