newbie has problems w/ dialup

[Bob Elzer]

Well it sounds like he doesn't have a choice, that's why he posted the
question.

I imagine he is using ppp to dialup, in which case mru and mtu would matter.

Also comparing the modem initialization strings for each system, might help.

Knowing those settings would help too.

For a 56K serial modem, the thing to do was to set the speed to 115200, not
57600.  This allowed compression on text data, so you could get almost
9K/sec on ASCII text.  Whether this has any relevance to a USB device, I
dunno.  I got some proper bloody bandwidth in 2002 and haven't looked back.
Dialup's just too limited unless you're out in BFE and can't get anything
else.

MTU should be 1500.  MTUs shorter than about 1492 can break things, though
they shouldn't.  The old "16550 16 byte rx/tx buffer" thing is irrelevant to
a USB device, or should be.

The OP mentioned YaST.  I have not ever been impressed with SuSE as a whole,
since it seems to have more weird bugs than most other distros and has been
that way since 1999.
