Mine are obviously a FIFO overflow. sio1: 1 more silo overflow (total 7) They don't happen alot, but when I do a remote CVS and/or CVSup update from my mirrored repository over the 28.8K link to a box at work they tend to show up. Again, I've got NS16550AFN parts on my box, which are the old but very real good National parts, bought by my good buddy Jaye Mathisen at MSU a *long* time ago. > serial port used for kernel PPP is cuaa1, since it has a 25-pin > connector, and its locked at 57600 with a 28.8K modem.
