C-Kermit on the university end. PC (old Compaq 386/16) running ProComm
Plus, which includes something called "Super Kermit," on my off-campus
end. The modem is a Best Data Products "Smart One" 1442F internal Hayes
clone faxmodem.
Both ends are set for 19200 baud, and that lie makes the theoretical
throughput at 14400 baud about 73% efficient. I'm transferring compressed
binary files (*.exe, *.zip, &c.) from my campus home directory on a
lightly loaded machine to my PC hard disk, over a quiet phone line (0
packets resent).
Why am I getting only between 20% (with my modem compression enabled) and
30% (disabled) efficiency. I do understand why my efficiency improves
when I don't try to compress a compressed file -- I don't understand why
it is so low overall.
The STATISTICS command shows that I'm passing back a 90-byte packet for
each one I receive. Is this the fastest way to do Kermit?
Given the primativeness of the "Super Kermit" on my end, what can anyone
suggest to increase efficiency?
TIA.
