The IPX and SS2 are the fastest stock sun4c systems (40 MHz). If it's still
   unusable at 38400, we still have a ways to go.


my IPX was unusable at 38400 for some time, then i got an SS2 and moved
my modem there, and it was OK.  it is better now, since charles fixed
the new zs driver (ie, making him fix his problems.. :-)  BTW, the IPX
has no DTR!


then again, i *still* got better zs performance 18 months ago than i do now.


sigh.
