- Stefan, I'm not sure we're talking about the same thing here, but I
- just did a pppstats 0 after grabbing my mail and 2 files from St. Louis.
- I have 32 checksum errors logged so far, and that is about typical for that
- amount of data, 48 mails, and 135 news plus 150k of data in files.
-
- I thought maybe the new ppp 1.38 thats out for beta might fix some of it,
- it did seem to crank up the speed a bit. HOWEVER, at least using dialup, it
- can't hang up the modem without crashing the system. 3 times I asked it to
- hang up, 3 times it sent a bit of data to the modem, and 3 times it
- crashed. Thats enough for me, so I'm back to my registered 1.30.
-
- I have made the remark to my isp (both of them) that one of us doesn't
- know how to calc checksums. I get just as many errors on a local line as
- this quasi long distance. I can't believe the error rates would so closely
- match from 2 different isp's and 3 different locations. Take the remark
- about crc's for what its worth, which may be nothing.

- Cheers
