Dear Net people and Kermit hackers ( in the old sense of the word,
please! ),
I am in a quandary...
If i set my pratical periperals modems to factory defualts, and then
use x-on xoff flow control as demanded by VMS's hacker ( ok, new sense
! ) evasion, then all is very nice, no errors, but if I xoff and try
to stop the flow of data to the screen, there is a humongous buffer in
the modems somewhere of data already in the pipeline that will not
respond to the xoff..
On the other hand, if i take all error corrections off and make the
modem try to be a direct wire, i can xoff and xon nicely, but errors
abound as in Psalm 19:12 "Who can discern his errors? ... " 8-)
So, after downloading a 200 page paper from Practical Periperials,
I'm throughtly confused... Should I enable all error corrections, and
then enable pass-thru xon xoff via the Q commands??? Or am I still
talking moonshine?
My Old setup was 19.2 Kbaud ports on the DECserver, 1.44 pp modems,
and generic whatever to dial in, testing with pp modems.. I'm open
to change/ideas.
Jim
