The DB9 is a nice car manufactured by Aston Martin. What you have
on the PC is a DE9P (D shell, size E, 9 pins).

The U5 serial port A is a DB25S (D shell, size B, 25 sockets).
The U5 serial port B is a DE9P (D shell, size E, 9 pins).
Serial port A:

If you want to use the PC as a serial console then you need to use
serial port A.

The U5 keyboard/mouse connector is standard RS232 protocol using TTL
standard signalling levels. The PC PS/2 keyboard and mouse connectors
are a proprietary protocol. They are not compatible. There are
converter boxes on the market that sits between the Sun machine and the
PS/2 keyboard and PS/2 mouse. Examples is the APSSUN on
