-
- The Niscan/GS scanner driver provides Black and White, Halftone and Gray Scale
- scanning for all ZSoft products. The driver consists of two parts, the Niscan
- supplied NISCANGS.SYS and the ZSoft SAPI.EXE driver. See SAPI.DOC for more
- information on using the SAPI.EXE scanner driver.
-
- This driver supports the following features:
-

-
- /A=xxx Sets the base I/O address of the scanner. The two valid
- settings are 250 and 350. The default is 350.
- /I=x Sets the interrupt request number (IRQ). The valid settings
- are 3, 4, and 5. The default is 3.
- /D=x Sets the DMA channel. The valid settings are 1 and 3. The
- default is 1.
- /T=xx Sets the scanner timeout period. This is the time in seconds
- the scanner will wait for scan activity, once a scan has
- started. After the timeout has expired, the driver signals the
- application program that the scan is complete. If this
- parameter is not specified, a value of 0, meaning "no timeout"
- is assumed.
- /N=x Adjusts the timing of the scanners optics. The valid values
- are 0 through 7. Zero is the default. If the image provided
- by the scanner appears to have a wood grain quality, vary this
- parameter. Although the correct value varys from PC to PC,
- the most commonly used values are 0, 1, and 7.
-
- The adapter card has a DIP switch to set the I/O address, DMA and interrupt.
-
- 1 = ON IRQ 3
- 2 = ON IRQ 4
- 3 = ON IRQ 5
- 4 = ON DMA 1
- 5 = ON DMA 3
- 6 = ON DMA 1
- 7 = ON DMA 3
- 8 = ON Addr 250 OFF Addr 350
