I'm hoping Debian users can give me some insight to a problem I have with Knoppix 3.8 installed to hard disk.

I've used the kppp setup and modem setup tools to configure Kppp to dial out. I've used the same information I use on my SuSE partition (where I don't have such problems as I'm reporting here).

The modem dials out, connects (no errors), pppstatus tells me the baud rate is 49666, but the speed is less that 1 kb/s.

I've used stty and setserial to check/set the /dev/ttyS0 settings: baud_base 115200, speed spd_hi (57.6 k, slightly more that the 56 k rating of the modem: US Robotics Voice/data/fax).

It seems I can connect to my ISP, but the modem output is much too slow.

Any ideas on how to speed things up?

I just switched to a more recent version of KDE, and had an extremely slow dialup connection (US Robotics PCI modem)

I went into KPPP configuration and changed the connection speed listed there from 460,800, to 115,200

It seems to have fixed the problem.

Actually, there are two speeds to consider: the speed of communication between computer and modem, and the speed of communication of modem to outside world. The first is the baud rate; the second is speed (to use the correct terms).

My baud rate is set at 115,200 (same as my SuSE installation) . The second is set at spd_hi. There is the problem. It isn't working properly. It is extremely slow, and I am at a loss for ideas on what to check next.
