HSS8 Windows NT 4 Software Driver Protocol Settings

The HSS8 has eight serial communications controllers (SCCs) [Channels 1-8] that support UART and
HDLC/SDLC protocols, and four serial management controllers (SMCs) [Channels 9-12] that support only
asynchronous UART.

The control panel applet allows the user to set all the protocol-specific options available on the
HSS8 communication controller chip (the MPC8260 PowerQUICC II™). For available options for each of the
fields, see [2.1.1].

This section details the information used by each protocol and explains the use and limitations of every
member.

5.1

Protocol Selection

Each Channel must be configured to use a protocol.

Protocol :

UART
HDLC
BISYNC
SMC_UART

The protocol settings for the device can be set through a control panel applet. Access the applet by clicking on
the Start menu and selecting the Control Panel from the Settings option. Click on the icon shown in Figure 2.

5.2

Using the Control Panel to Change Channel Settings

The control panel applet selection boxes list available options for the specific protocols. Options that are not
available for the selected protocol are grayed out. All the options (including the options in the Advanced
dialogue) must be entered to create a valid protocol setting. Always click the Apply button before closing any
of the dialogue windows. The settings are applied to the HSS8 Channel when it is reopened.

When “Lock Settings” is checked, all requests via the Win32 API will be ignored. Any change in baud rate or
parity will then not be updated, the HSS8 Windows NT 4 Software Driver will keep the setting as specified in
the control panel. When the settings are not locked, the baud rate, etc. may be updated via the Win32 API
functions.

When using the HDLC or BISYNC protocols, it is recommended to use the “Lock Settings” option.

The settings are stored in the Windows registry, under the keys :

“HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HSS8\DeviceX\PortX”
