- Well, I have a 80486 that runs at 33 Mhz and has 16 Megabytes of RAM installed
- on it. I use 9600 baud with v.32 v.42bis as well.
-
- Anyway, my system will "trash" a transfer if I am doing just about anything
- else at the same time. First I was using a Windows term program because
- I liked it. But that didn't do background downloads as I had hoped. So
- I switched to TE/2 and stepped the priority all the way to the top! Now
- I get the same problem, it just takes longer for it to occur, though.
-
- Oh, and I use YModem-G with 1K packets whenever possible. But if I go with
- just YModem and 1K packets, I don't have this problem, but transfers take
- approximately twice as long. No fun at all.
