Pins on the TTL connector of the
DS1206N-TM and "-TS"
"Available signals" column shows a particular combination of I/O lines for each
option. For example, option 0 defines the standard serial port arrangement with RX,
TX, CTS, RTS, DSR, and DTR lines. Option 2 gives you one channel with RX, TX,
CTS, and RTS lines, one more channel with just RX and TX lines, and yet another
channel with a single RX line. The TX line is "missing" because, once again, there are
only three outputs available. This is why this line is shown in grey lowercase (tx).
