Three Ethernet LEDs, LED3, LED4, and LED5, driven respectively by the LXT971A LED/CFG(1:3) outputs, are provided on the front panel.

TTY Console Serial Port

The SMC1 part of the CPM is used as a simple asynchronous serial port for connection to a TTY console. An on-board RS232 transceiver translates the signals to RS232 electrical levels which are routed to the 2.5mm stereo jack connector J4.

User-Programmable LEDs

Five user-programmable LEDs (CPU_LEDs) are provided: four on the board, and one on the front panel. They are controlled through CPM I/O ports used as simple outputs.
