Well, rumor has it that ProTerm v2.1 (if it's officially out)
supports Zmodem file transfer.  Zmodem is what is called a
"streaming" protocol, as compared to a "packet" protocol.  All it
really results in is computer A sending the data in a continuous
stream, and computer B telling A when it detects an error.  Sortof.
There's just one catch to it - if you have a noisy phone line, it
REALLY sux.  However, in this age of error-correcting modems (such
as MNP-style modems; the newer 2400 & all 9600's that I know of)
it should prove to be beneficial.
 
Hope this helps!
