When you go through a 3270 emulator, you're at its mercy. This is a perfect
example of why Kermit lets you specify the packet length, and why it uses
a short default packet length. If longer packets kill the 3270 emulator,
then that's all there is to it.
Preliminary reports indicate that Cisco release 10.3 will let you transfer
files through its 3270 emulator with packets up to about 1900 bytes in
length. That's a big improvement.
