The subject title sums it up. Using C-Kermit for os/2, v5A (191), seems
to be overall slower than using kermit for dos v3.16 (or even v3.14). For
example, I am writing this using C-Kermit, under os/2, to log in to the
computer at U of W. As I type, the delay between striking a key and its
echo on screen must be about twice as slow as it is when I do the same
thing under dos + mskermit for dos. All of the settings, as best I can
tell, are the same. Moreover, file transfer seems somewhat slower under
C-Kermit, though I have not tested this yet. (Actually, I do have some
emperical evidence. For varios reasons, I had to download a huge biniary
file. Under mskermit, I was getting about 3(+) k cps; under
c-kermit, exactly 2.5 k cps plus/minus 5cps, c-kermit gives one a lot of
data.) Any ideas as to this discrepancy?
Now on a different matter--file transfer. I have a 33.6 Digicom
modem. Yet even after tweaking Kermit (Dos or C- versions) I cannot seem
to get much more than 2500 cps rate for binary file tranfers. (Somewhat
faster, of course, for text files.) Now surely there must be a way to get
faster transfers, even over the ordinary phone line that I am using (it
seems to be a fairly clean connection). The UW modems are relatively fast
at least 19.9 or 28.8.
I would very much appreciate any suggestions for improving this
performance. Of course, my experience may be `normal', then I would like
to find that out too. Perhaps we can take a pole...
