I use pppd (kernel-based ppp) with AST clones (16550s) and cyclades. Both work well, but I feel that the cyclades are a little better. A heavily loaded 486-33 with 20 busy links at 57600 on cy0, cy1 (ISA) consumes about 25% of CPU in servicing interrupts. Rule of thumb ratios indicates the same load would occupy about 3% of CPU on a P133. There is a now a driver for PCI-cy, but that is in -current, and not in 2.1.5R, I believe. Danny
