* DB9 signals DCD, DTR and DSR (pins 1, 4 and 6) are
internally shorted together to provide a hardware flow control
loop back to the DTE.

Solder Terminal T7 is provided as a spare. It is designated as
a general purpose input to the GT47 when soldered to the blue
flying lead of the developer’s kit cable (which connects to
HD15 pin 15).
