Appendix A: Cable Charts
All charts give full pinouts. Only pins 2 & 3 are required for basic
operation. Pins 7 and 8 are needed for hardware (RTS/CTS)
handshaking. If the connected device requires DTR or DSR, these
signals are available on pins 4 and 6 respectively. See Appendix B
for a block diagram of the 232BRC.
