Use a full-handshake (includes RTS and CTS) PC modem serial cable for a modem with
RTS/CTS flow control. Table A-7 shows the cable connector pin assignments for this
cable.
You can use this cable for all serial devices except those that do not need RTS flow control.
If you add a null modem adapter to one end of the cable, you can still use it with devices
like serial printers and dumb terminals that do not need RTS flow control. You can
purchase the full-handshake PC modem serial cable from SGI or your local service
provider.
