Don't you need "set send packet 2000", as well?
After a short session, use "statistics", or "show statistics" to see how
many windows were used, and what packet size was used. You might need more
than four windows, but probably not.
What I found a while back is that my UNIX box had an 8-bit 3C503 card, and
kermit transfers were very poor, although FTP was good (Novell LAN FTP).
With my current mix of 16 and 32 bit ether cards, the Windows-for-Workgroups
FTP, the Zmodem/Kermit/FTP in ProcommPlus, and MSKermit 3.14 all transer at
good rates. FTP is the fastest of the bunch, but Kermit is not off by much.
You should turn off the display if you are transferring large amounts of
data. "set file display fullscreen", which normally is so informative on
a modem connection, wastes a lot of time at high transfer speeds.
And if all else fails, try XSEND, a utility available on columbia, intended
for use with Kermit, that will also spit out ftp command sets, to transfer
an entire hierarchy.
