Intermec 6100 Reference Guide

R

Several 4000 Series Video interrupts are supported for the 6100 Computer.  The

supported interrupts are listed in the Interrupt CrossĆReference table, located unĆ

der the Interrupt CrossĆRef (by number) tab.  Even though they are matrixed into

the entire set of interrupts, each individual interrupt supported by the video

drivers, VROTATE.EXE and FONTSEL.EXE can be identified by the notation,

VROTATE, immediately under the interrupt heading.  There are one or more

reference tokens for each of the interrupt definitions, to accommodate interrupts

supported by one or more applications.
The categories of interrupt services are listed in the center column of the followĆ

ing table.  Individual interrupt definitions can be located:

"

Using Table 6Ć4 (by keyword) listed in the right column, and searching for

them in the Interrupt Index.  Most nouns and verbs can locate an interrupt

definition using the Interrupt Index, with the exception of Set and Get.

"

Using the Interrupt CrossĆReference table

or just thumbing through the definitions, searching for the notation, VROTATE.
