    Assignment consists of the module number (1 to 6) and the port number (1 to 4) that the printer is physically connected to on the Model 24SII DES. The Default Printer Assignment may be set to 0 for contention mode in which case all print jobs sent from the particular computer will be sent to the first available printer.

  • Page 68: Modem Sharing

    A common mistake is to configure your communications package to match your modem's serial parameters (baud rate, word size, etc.) and not the Model 24SII's serial parameters. Keep in mind that you are physically connected to the Model 24SII DES, not the modem.
  • Page 69 However, you would configure your modem communications package to communicate at 9600 baud to match the baud rate of the computer port on the Model 24SII DES you are connected to. You are now ready to make the connection to the modem port through the Model 24SII DES.

When the peripheral device can receive more data, the Model 24SII DES will expect to see a high on the CTS line.
