Software Manual 17

3.4 SCF Drivers and Descriptors

• scrmon

Depending on the setup of the RMon, the VGA monitor/AT-keyboard or

one of the serial channels may be used as console. The console is

implemented as SCF device with the device driver scrmon, which

operates in polling mode. The console device descriptor name is always

term.

Using scrmon makes sure that the OS-9 configuration adapts to the

RMon configuration.

• sc17cons

This is the interrupt driven driver for the MF-2 keyboard and the

graphics. The driver needs a kbset module, so one of the following

modules from /dd/CMDS/BOOTOBJS has to be loaded:

kbset_us standard US keyboard set

kbset_ger german keyboard set

kbset_mgr keyboard set for MGR US layout

kbset_mger keyboard set for MGR german layout

Additionally, the driver needs a font module. Select one of the following

fonts and load it to your module directory from /dd/CMDS/BOOTOBJS:

font_9x18

font_7x14

font_11x20

The resolution and refresh rate of the graphic interface are taken from

RMON’s parameter RAM.

This driver should be default.

See appendix A for a detailed description of the control sequence codes.
