That makes perfect sense: LAT is designed for a LAN while CTERM is a general purpose WAN protocol. So the surprising part is that LAT works as well as it does over a WAN. The reason probably is that modern WANs have performance (latency, in particular) good enough to match the "LAN" expectations of LAT.

Look at it this way Sampsa: LAT degrades by a factor 3 while CTERM is better than half the performance.
LAT nor CTERM know they're travelling over an extended LAN.
So I'd think CTERM behaves better than LAT :-)

So just for fun I did some speed experiments with CTERM and LAT using Kermit to send the same file.
WAN connection is KUHAVX (Finland) to RHESUS (UK).
CTERM
LAN: 30,000 CPS
WAN: 16,400 CPS
LAT:
LAN: 100,000 CPS
WAN: 30,000 CPS
So LAT is as fast over a WAN link as CTERM is over a LAN..What's wrong with CTERM?
