Well, speaking from Sun experience - so how applicable this is really
depends on how thoroughly Sun-compatible the Axil is - unplug the
keyboard and plug into both serial ports (Suns have only one DB-25
which carries both serial ports, with port B on what RS-232 calls
"secondary" signals; eg, ttya CTS is on pin 5, where you'd expect CTS
to be on a DB-25, while ttyb CTS is on pin 13, which RS-232 calls
"Secondary Clear To Send" - I don't know whether the Axil does too).
You may need to fiddle baudrates to get comprehensible output.

Some failure modes will, for example, print something on ttyb but
nothing else, depending of course on the ROM version and the exact
failure.
