CPCHND.SYS Documentation

CPCHND.SYS is a DOS device driver that allows the Complete
PC Scanner to be used with PC PaintBrush with INTERRUPTS.
Dither and Brightness are set on the scanner itself.
Resolution is dependent on the scanner type:

Scanner Resolution(s) in DPI
Complete Hand Scanner/400 400,300,200
Complete Half Page Scanner 200
Complete Half Page Scanner/400 400,300,200

It is unnecessary to run the bundled software that comes with
the Complete PC Scanner. Insert CPCHND.SYS into the CONFIG.SYS file
using the appropriate options. At boot the driver will respond with
a message based on the options. When PaintBrush is run, the scanner
will light up briefly before the tools are drawn on the screen. If this
happens you are in buisiness. If not, you must power down and re-address
the dip switches and try again.

Options are:

Default Complete Hand Scanner/400
/1 Complete Hand Scanner/400
/2 Complete Half Page Scanner
/3 Complete Half Page Scanner/400
/C channel for DMA, 1 or 3 (default is channel 3)
/H hex port value, default is 3E0H (no 'H' needed)
/I irq number 2-5 (INTERRUPT number is required)

Examples:
device=cpchand.sys /2 /H2E0 /I2 /C3
Complete Half Page Scanner, port = 220H ,IRQ = 2, DMA=3

Available Port Settings:
220H 260H 2A0H 2E0H 320H 360H 3A0H 3E0H
