FNX6809 GraphicsVTIOCalls

Graphics Summary

Use the fstatus command in Level 2 to see the current status of the graphics registers.

There is a default clut memory module included called xtclut in CMDS. This has the xterm colors according to this chart

vtio Get/Set Stat Calls

SS.AScrn

Allocate a bitmap screen

Entry: R$Y = bitmap# (0-2)
       R$X = screentype (0=320x240, 1=320x200)

Exit:  B = A non-zero error code.
