I'd really like to see the design scheme all-sufficient without the note. The note may clarify the scheme and help the reader to comprehend it, but the note should by no means be crucial to follow the scheme. It is the matter of adding a mere row to the table: ... DTR 20 connects to 6 DSR DTR 20 connects to 8 DCD DSR 6 connects to 20 DTR DCD 8 connects to 20 DTR The reader is free either to install an internal strap between pins 6 and 8 in each connector or to use two pairs of wires to connect pins 6 and 8 on each side to the single pin 20 on the other side. -- Yar
