ppp - packet loss

[Hugo van der Merwe <hugovdm@mail.com>]

I have run out of ideas on what to check. I have a laptop here (Pentium
120) that always has a packet loss when dialing into my isp. (External,
serial port modem.) It runs potato. I have used the same modems (two of
them), on a desktop, and the faster of the two, on another laptop
running woody, with the same isp, same dial up number, with no problems
whatsoever, so the problem cannot lie with the isp/modem/modem cable.

How can I diagnose this problem?

Thanks,
