This section contains cable pinout information for serial cables that you can connect to your O2+ workstation. It also describes Silicon Graphics serial port converters. The following topics are covered:
For serial printers and dumb terminals, use a 3-wired standard PC cable. Table A-12 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 see the man page, from the Toolchest, select Help > InfoSearch > Man pages. Or place the cursor in the console window and type: man serial |

Use a full-handshake (includes RTS and CTS) PC modem serial cable for a modem with RTS/CTS flow control. Table A-13 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, select Help > InfoSearch > Man pages. Or place the cursor in the console window and type: man serial |

The O2+ workstation's serial ports conform to the PC standard pinout for EIA standard RS-232 signals. The transmit and receive circuits are also capable of higher speed signalling according to the EIA RS-423 standard. You can also convert these signals to support other interfaces.
SGI offers two converters: one for the RS-422, commonly used for video deck control, and an Apple Macintosh to MIDI converter for the RS-422-like signalling used by MIDI devices to connect to Apple Macintosh serial ports.
The Silicon Graphics RS-422 converter converts the O2+ workstation's RS-232 Transmit Data and Receive Data signals to SMPTE 207M-compatible RS-422 for video deck control.
Table A-14 shows the pinouts for the O2+ workstation end.
