This newsgroup has long been replete with advice on high-speed data transmis-
sion (FOSSIL drivers, wringing a bit more throughput out of a 'Blazer, etc.). 
But for the sorry band of impecunious Wafflers who fall below the 9600-bpi 
poverty line, precious little information appears to be available on how to 
make Waffle work efficiently with an MNP modem.  A few hints are scattered 
through the documentation (the most pertinent of which, surprisingly, seem to 
be those in TELEBIT.DOC), but the subject isn't covered in any depth, as far 
as I can see.  The transmission speeds I'm getting definitely leave something 
to be desired.  (My machine is a turbo 286, and my all-time best result was 
217 cps on a UUCP file copy with compression enabled.)  I realize that many 
factors that influence transmission speed may be related to the remote ma-
chine and therefore beyond my control, but I'd like to at least make sure 
that I'm not doing anything stupid.  So if there's an MNP expert out there 
who would be willing to critique my DIALERS file, I'd appreciate it very 
much:

I've been using EvMNP to communicate with my newsfeeds and EvMNP5 for email
and file transfers.  In my STATIC file, I have both SPEED and LOCKED set to
4800.  (But I don't really understand what the SPEED parameter is for, nor
do I understand the function of the speed field of the dialers script.  Both
seem redundant if LOCKED is set.)
