Re: fastest serial speeds through ppp and/or pppd?

[Diana Eichert <deichert_(_at_)_wrench_(_dot_)_com>]

per a suggestion to look at http://www.byterunner.com/

i've ordered a single port 16650, clock multiplier selectable, card

sounds like it should be able to support 230k-460k rates, with the
interface set at 115k and it multipled on the box.

guess i'll see how it works when it gets here.

thanks everyone
