Using kernel 2.2.1 and the latest PPP (2.3.5 I believe) with an internal
56K modem.

1) Is there any way to determine the current, instantanious connection
speed that the modem is using? It may connect at 56k, but is there any
way to see if the _current_ connection has (say) downshifted to (say)
14.4k because of line noise, etc?

2) My normal connection sounds like this:

<dials> - <picks up> DEEDEEDEEdeedeedeeDEEDEEDEE*static*-<silence> and
then the PPP connection is negotiated, and life is good.

Once and a while, I'll get this:

<dials> - <picks up> - <pause>deeDEEdip - <pause> - DEEDEEDEE etc.

The PPP connection negotiates fine, and the log indicates the
local/remote IP addresses, but pings to the remote host vanish into a
black hole. The outgoing packets seem to be transmitted OK, but nothing
ever returns, and the connection drops after a few min.

The solution is to keep re-connecting until you hit a modem that doesn't
have that funny silence-deeDEEdip-silence-connect sequence. Annoying as
all hell.

Anybody recognise what's going on? What logs could I generate that would
shed more light on the problem than just my onomatepeic representations
of modem connect sequences?

Thanks,

DG
