Serial Ports

The Octane workstation serial ports can operate in one of several modes:

  • RS-232 electrical levels with a standard PC pinout.

  • Macintosh style electrical levels and a Macintosh-compatible pinout. (This mode requires an additional adapter cable. See “Serial Port Adapter Cables”.)

  • ANSI/SMPTE 207M electrical levels and pinout. (This mode requires an additional adapter cable. See “Serial Port Adapter Cables”.)

This the PC-compatible pinout. The range of supported baud rates is 300 baud to 460Kábaud.

Serial Cables and Adapters

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:

Printer/Dumb Terminal Serial Cable

For serial printers and dumb terminals, use a 3-wire standard PC cable. TableáC-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


man serial

PC Modem Serial Cable

Use a full-handshake (includes RTS and CTS) PC modem serial cable for a modem with RTS/CTS flow control. TableáC-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.


Note: If you are attaching a modem with modem signals and RTS/CTS flow control, you must use the /dev/ttyf* command devices in the configuration files. For more detailed information, see the serial man page. To access this man page, from the Toolchest, choose Help > InfoSearch > Man pages. Or place the cursor in the console window and type

Serial Port Adapter Cables

The Octane workstation's serial ports conform to the PC standard pinout for EIA standard RS-232 signals.

The purpose of the adapter cable is to allow the Octane workstation to use standard PC or Macintosh serial devices.
