No Sun has fast serial ports, except the PCI based Sun's.

If you have an sbus Sun, the only way to get fast serial ports is to buy
something like a Magma serial port card.

I've been trying to get one for 2 years now.  The only ones I can find,
the owner wants too much for them.

It's sad, but I can pick up an old PC for nearly nothing, which will do
the job just fine, and for far less money than a decent serial board for

If you want a Sun which can run a fast modem (or any fast serial link)
with on-board ports, you need to get one of the PCI machines.  For
example, the U30 can run its serial ports fast.
