so, it seems its more of a modem connection problem then a network
protocol/performance problem..Do you have a shell or ftp access to a
machine on your isp's network? its a good test to try to d/l something
off the isp's network..i bet the admins there would be willing to throw
something up on anonymous ftp for you to get for testing.

to be honest i dont know :/ its been SOOOO LONG since i used a 14.4k
(~1994) this is the init string i use for my k56flex/v90 modem(i know it
wont help you int his case but others may want, i found it makes for a
VERY stable and fast connection)
AT +MS=12,1,40000,56000 E0 V1 &D2 &C1 W1 S0=0 S95=47 S202=32
(S202 is an undocumented feature)
as for the AT commands, i got a PDF file here you can download and
read.. http://www.firetrail.com/~aphro/atmodem.pdf it explains everything
rpretty much. the admin at my local isp here helped me out a lot in
getting a good string goin, im lucky to have such a good admin down here
:) i forgot most of my modem stuff when i quot BBS'n back in '95.

that is possible ..i can personally report very good results with USR and
Zoomtel and GVC modems under linux.
sorry i cant help much more :<
