Hi...
Just over a month ago, I upgraded my systems modem from an
external 28.8 to an internal 33.6. The modem is called a Magitronic
and that's about all I know about it. Standard modem manual comes with
it...
The problem is that it randomly hangs. It doesn't hang up or
anything, it just sits there and no data goes across the link :(
I got the reseller to send me a new modem, which I've just installed,
and get the same 'hang'.
I've tried looking into the modem settings, and there really doesn't
seem to be anything there that seems, to me, out of the ordinary. Hardware
flow control is on, DTE is set at 115200, connection comes up clean, or so
it seems...
So, I figure I'm down to a general problem with my provider (Netcom.ca,
whom I wouldn't quite consider close to problem free in the first place...but
I *never* had a problem with my 28.8 modem...) or with FreeBSD...
Someone once mentioned that FreeBSD 'triggers' the FIFOs very high
in comparison to something like Windows, so I may be getting buffer overflows
that it can't recover from...but I get nothing in /var/log/messages that I
would expect to back this up...
Can anyone suggest what I might want to look into to determine which
end of the connection is having the problems? All I know now is that no
packets are getting through.
Oh, running FreeBSD 3.0-CURRENT with ijppp for connecting...
