This section contains cable pinout information for serial cables that you can connect to your Octane workstation. It also describes Silicon Graphics serial port converters. The following topics are covered:
For serial printers and dumb terminals, use a 3-wire standard PC cable. Table C-10 shows the cable connector pinout assignments for this cable.
![]() | Note: For a 3-wire cable and no hardware flow control modem, you must use the /dev/ttyd* command devices in the configuration files. For more detailed information, see the serial man page. To access the man page, from the Toolchest, choose Help > InfoSearch > Man pages. Or place the cursor in the console window and type |

Use a full-handshake (includes RTS and CTS) PC modem serial cable for a modem with RTS/CTS flow control. Table C-11 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. Devices like serial printers and dumb terminals that do not need RTS flow control can still be used with this cable provided that a null modem adapter is added to one end of the cable. You can purchase the full-handshake PC modem serial cable from Silicon Graphics or your local service provider.
