Well I found that PEP got around 18000 bps on my very noisy toll connection
to my news feed. It sometimes went down to 9000 bps but when I lost the PEP
modem on the other end I had to go and use V.32. I never once got this to
work over the toll line and always have to use the V.42 error coreection to
get a good transfer. I have never once got any errors come through with the
PEP but with the V.32 with V.42 the transfer sometimes stops in the middle
of a file and hangs there. Most times it starts up again with a barrage of
wrong packets sent but sometimes it drops the connection (PEP has never
dropped a connection).
