- The answer to this is more likely to be in your winsock software than
- a modem conflict. The reason why I say this is because of the Frame
- Check errors which is not good and is caused by the winsock settings
- not correctly set. This will most definetly cause your computer to
- lock up if it receives too many Frame Check errors. First, check to
- see if you have more than one winsock.dll on your hard drive. You
- should only have one that came with the connection software that you
- use. If you find extras then you could rename them.
-
- The reason for the Frame Check errors is because of your winsock
- settings. If you are using Trumpet Winsock then TCP MSS should be a
- minimum of 212, MTU = TCP MSS + 40, TCP RWIN = TCP MSS *4. My
- settings are MTU = 1420, TCP RWIN = 5680 and TCP MSS = 1380. The only
- way of getting these right is by experimentation. Might want to check
- the winsock newsgroups on this. Wirte down your original settings.
-
- Some winsock.dll files are also kind of flakey, especially the older
- ones. I do have some trouble uploading files with Trumpet Software's
- winsock.dll in which the computer will lock up. I compared Trumpet's
- winsock and Quarterdeck's winsock on uploading a 1Meg file to my
- server. Trumpet's winsock locked up on 3 of 3 tries and Quarterdeck
- uploaded completely every time, although it seemed slower in
- uploading.
-
- I hope this helps you.
