A 16550 is clearly a big help, but Microsoft admits that their
comm.drv fails often when you are using speeds greater than 4800. I have
16550's in my PC. A step in the right direction is TurboComm, a replacement
driver, but that is expensive. A hardware solution is to use an intellegent
serial card, like Hayes ESP or Telcor's T/Port. An O/S solution is to use a
real operating system, :-) I want a no cost, MS-Windows solution.
But I think folks read too much into my use of "robust"
NUpop works fine as a DOS program without end-to-end.
I simply want that functionality in a Windows program. No more, no less.
I'm aiming low end, the mass market with a 386sx and a 2400 modem. Folks
like me with a network of PCs in their house and even cypherpunks are not
my market. The English majors, history and art majors are the folks I
envision when I see a "user"
