Very Computer

It would be great if someone could let me know why my dial up connection
with kppp is much slower than with wvdial. I have the same
initialization strings, but when I use wvdial from the commandline I get
higher transfer rates and better response in Browsers than with kppp.

This doesn't make sense to me when I initialize the modem with the same
strings.

Check to make sure that the other data relating to the various links is the
same including options such as the MTU and MTA values.

See ya

Both wvdial and kppp are frontends to pppd.  Just because you supply a
modem string to a configuration program for these doesn't mean that it
configures only those strings.  The device file configuration (/dev/ttySx)
can be fouled up by one of the configurations.  Pppd modem to computer
speed can be different (pppd speed option).  Small MTU and/or MRU (pppd
options mtu and mru) can restrict speed somewhat.  (I have no idea what
another poster meant by MTA but, whatever he meant, it is very doubtful
that it would apply to a regular PPP connection.)

If this really concerns you then you'll have to post more details in
the form of option files, device file configuration, chat -v (or use
the equivalent verbose option for the frontend's dialer) and pppd debug
log messages.  Exact copies, with timestamps, not hand copies.

You also need to be more specific about "higher transfer rates," which
is too subjective.   Use pppstats to measure an FTP download for each
frontend to get hard numbers.
