Adding serial and parallel ports

Configuring a serial card

Upon startup, if the Serial Manager detects any PCI serial cards that have not yet been configured, it displays a pop-up window asking if you want to configure them now. If you select yes, the Serial Manager automatically assigns the appropriate configuration values and generates device nodes for the cards.

You can also use the Serial Manager to configure a non-PCI SCO OpenServer-supported dumb serial card on your system:

  1. Start the Serial Manager.

  2. Click on Add and choose a board from the list that has a free unit number. Some serial cards are listed several times because they have several possible base I/O addresses.

    NOTE: Serial boards can only be configured on COM ports that map to supported unit numbers. Depending on the capabilities of the boards installed on your system, you might need to disable a board on an existing controller or add a new one. For example, if the board you wish to add is listed as supporting only unit 0 or 1 and there are already boards configured on those units (that is, on COM1 and COM2), you must disable the board on unit 1 before configuring a new one. However, if the new board supports unit 2, you can configure that board at COM3.

  3. If necessary, change the interrupt vector (IRQ) and base I/O address settings to match those configured on the card. Possible interrupt and address conflicts are shown by a ``*'' next to the listed value.

    NOTE: If you select a PCI board, IRQ and base I/O values are dimmed out because they are assigned automatically.

  4. Click on OK when you have finished defining the serial card.

  5. If you want to change the speed or interrupt trigger level, or to enable or disable a login for any of the ports on a serial card, follow the instructions in ``Configuring a serial port''.

  6. Click on Close.

  7. If the Serial Manager relinks the kernel because you changed the configuration of the serial ports, you must shut down and reboot the system for the changes to take effect.

You can also modify the configuration of existing serial cards by highlighting the card in the ``Configured serial cards'' list and clicking on the Modify button next to this list. Change the configuration of the board, and click on OK when you have finished.

To delete a configured serial card, select the card from those listed, and click on Delete.
