I don't know if GV suports the +MS= or not.
Most of these work on my Blue G3 with stock internal Mac 56k modem.
I have a 26,500 foot phone line so things are a bit intermittent around here.
Lots of drops, lots of retriains, lots of days when the connection is a solid
as a rock at 28,800. Go figure. Cable modems? can't wait. sign me up!
If you're having trouble staying connected try pinging your isp's router every
few seconds. This seems to keep me going for some reason.
Apple has a book on their support site: AT commands for the Apple Internal
Modem.
ftp://manuals.info.apple.com/Apple_Support_Area/Manuals/other/ATCommands.pdf
I think the +MS commands below may be specific to a particular chip set. The
book details ways you can do the same thing withthe usual modem commands. the
+MS is newer. the usual commands set particular register values. Although
modem manufacturers differ, I'll bet many use the same chipsets.
An interesting commands to try are: ATI0 through ATI9 which reports back info
about the modem.
None of these init strings is guaranteed to work. some may not work at all.
right now I'm using: AT&FM0+MS=11,1,300,33600,0,0,28800
AT&F1\A0X4%E2&D0L3M2+MS=11,1,9600,14400,0,0,14400
AT&F1&D0-K1+MS=11,1,9600,14400,0,0,14400
AT&F1M2L1&D0-K1+MS=11,1,300,28800,0,0,33600
AT&F+MS=9,0,9600,9600,0,0,14400
AT&F+MS=10,0,14400,14400,0,0,14400
AT&F+MS=11,1,300,33600,0,0,28800
AT&FM0+MS=11,1,300,33600,0,0,28800
