Forcing modem connection to 57600 bps
After using my dial-up connecton with speed reporting I wanted to force
my modem up to it's maximum speed. It works from windows side, so, it's
just up to configuring it also to Linux. Windows doesn't help, there is
just one box where to check as "[] use always this speed", no AT
commands found there (was that really a suprise?).
By the way it's internal ISA modem named
SupraExpress 56i SP Intl
So, I went to look modem's AT manual and edited /etc/chatscripts/
I added AT+MS= part just before number dialing.
I don't know do I use wrong AT command, or are parameters wrong,
anyway it calls, but not connect.
By commenting that out, everything works like earlier - giving usually
48000 or 46667 connects.
Any ideas where to look next?
/etc/chatscript/<script> is here

/var/log/ppp.log looks like that
