Disconnect the keyboard and mouse.
This will give the system no choice, but to use ttya.
Since you have diag-switch? set to true output should be coming out the
serial port anyway.
To be extra sure you can change input-device and output-device to ttya at
the ok> prompt.

Also make sure auto-boot? is false and/or diag-device is set properly.
The system will use the diag-device instead of the boot-device which is
usually set to 'net' by default.
I always set diag-device to be the same as boot-device especially on
servers.
