Data Bits, Stop Bits, and Parity
The format of the bit-wise transmission of data is determined by the data bits,
stop bits, and parity parameters. The default settings are 8 data bits, 1 stop bit,
and no parity. Check your equipment documentation for the proper settings.
1. Use the arrow keys to select the data bits for the port(s) from the list
displayed.
2. Press Enter. The stop bits prompt displays.
3. Select the stop bits (1 or 2) for the port(s).
4. Press Enter. The parity prompt displays.
5. Select the parity for the port(s).

6. Press Enter. The flow control prompt displays.
Flow Control
The device port flow control setting determines the method of flow control.
The two most common settings are XON/XOFF (software) and RTS/CTS
(hardware). The default setting for the device ports is XON/XOFF. Check the
equipment documentation for the correct flow control setting.
1. Select the flow control for the port(s).

2. Press Enter. The port type prompt displays.
Port Type
Each SCSxx05 device port is factory configured as a DTE device, ad each
SCSxx20 device port is factory configured as a DCE device.
Note: Make sure to select DTE if you enabled an operator port or group
of ports.
1. Select the Port Type (OFF, DTE, or DCE) for this group of ports. OFF
disables the port.
2. Press Enter. The inhibit buffering prompt displays.
Inhibit Buffering
By default, buffering is enabled (Inhibit Buffering is No). Inhibiting buffering
disables the buffering on a port, including bi-directional traffic that a system
administrator or user may record in direct mode. Therefore, a system
administrator may choose to inhibit buffering temporarily when entering sensitive
data, so the other users cannot view the data. Alert and panic messages from the
attached device are still stored when nobody is connected.
