MARS128.DOC
The MARS128.SYS is a driver for MarsTek's 128 hand scanner.
This driver has only two options:
/Cn Where n = DMA channel 1 or 3
/Hhhh Where hhh = a 3 digit hexadecimal port address.
The MarsTek 128 card can use port addresses:
100H, 200H or 300H.
Example CONFIG.SYS entry:
DEVICE=MARS128.SYS /C3
The driver is setup for the Marstek 128 and DMA channel 3.
This Marstek handscanner does not support interrupts, therefore
to obtain the best performance, MARS128.SYS requires EMS.
Paint Brush may save buffers to the hard disk during the scan.
When the disk is accessed, scanlines can be lost, resulting in gaps
in the image. The entire scan may be scanned to Expanded Memory and
then read back as required, greatly reducing the chance of losing
scanlines.
