At 38.4kbps, output looks smoother.  The pauses are still there between
bursts of output, but less noticeable.

Flow control didn't seem to come into play at 38.4kbps.  No sign of
lost characters, even with no flow control enabled.

BTW, is it just me, or does Sun do hardware flow control strangely?  Given
your experience, you're probably aware of this, but I've just discovered
that the RJ45-DB9 adapter that Sun supplies with their gear (530-3100-01)
is just plain weird.  It swaps the TXD and RXD wires (as a null-modem does),
but is otherwise straight through for all the control signals (RTS-RTS,
CTS-CTS, etc.).  A full null-modem arrangement (like the APACN 24490-71,
but with Perle JetStream pin-outs on the left instead of IOLAN) doesn't
let the data flow.

Thanks and regards,
