- We run a lot of 3c501's with NCSA telnet and i ran into a similar problem
- that was fixed by changing the MTU parameter in the CONFIG.TEL file
- from the default of 1024 to 512. This is apparently a Maximum Transfer
- Unit (packet size?) parameter. I don't know where the hang was happening
- but it always involved a 3c501/NCSA and has not recurred since changing MTU.
-
- Good Luck,
