Hello,
I just bought Newport Electronics iServer-Microserver device to convert
serial to Ethernet and ran into the exact same "lockup" issue that
Buddy and Stephmon saw... We've been running into the same problem for
a week or two, so I finally decided to do some Google searching.
Can you guys (or anyone else) comment any further on the subject? How
reliable is actually UDP (i.e. does it lockup too)?
Do you guys suggest that I simply go buy another box, and if so, do you
have any recommendations?
Thanx in advance 😉
