- The Niscan device driver SPECTRA.SYS must be loaded from CONFIG.SYS and be
- loaded before the ZSoft driver. The commands provided by the driver are
- listed below and must appear on the SPECTRA.SYS line of your CONFIG.SYS
- entry.
-
- /B=x Sets the baud rate:
- 0 = 9600
- 1 = 19200
- 2 = 38400
- 3 = 57600
- /P=x Sets the COM port number, where x is 1 through 4.
- /T=x 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.
- /S=x For 16550A serial cards ONLY. Sets the number of characters the
- COM port receives before issuing in interrupt to the driver.
- A value of 8 is recommended.
