The above pin assignment is standard for all Tibbo devices with the universal port
(for example, see the serial port of the DS1102).
LEDs
There are eight LEDs: five red and three green. Red LEDs are connected to TX, RTS,
DTR, FD/-HD, and -232/422-485 lines. Green LEDs are for RX, CTS, and DSR.
All LEDs are buffered (with logic gates) and light up for the LOW state of
corresponding control lines.
