that recognizes the Smart-Frame Protocol and communicates either
serially through a comm port or directly through the PC bus.
Installing a TAPI Driver
To install a TAPI driver, simply run the executable driver file with
additional command line parameters, if appropriate, from the DOS
command line. This loads the driver into memory as a TSR program.
SBC Driver
If you have set the I/O address or the interrupt number parameter of the
SBC to values other than the default parameters, or if you are using a
touch frame that has a different number of x-axis or y-axis beams than
the default, you must provide the correct values for these parameters on
the command line when installing the SBC driver.
The SBC driver command line has the following syntax:
SBC options
The available
options
are:
U
= Uninstalls the driver.
An
= I/O address.
n
may range from 200H to 3F0H. The
default is 300H.
In
= Interrupt number override.
n
may be 2, 3, 4, 5, or 7. The
default is 7.
Xn
= Number of x beams on frame. The default is 40.
Yn
= Number of y beams on frame. The default is 30.
Sn
= TAPI software interrupt.
n
may be the number of any
unused software interrupt. The default is 55H.
The command line is case insensitive and the command line parameters
may be arranged in any order. For example, to install an SBC driver
using an I/O address of 320H, interrupt 5, and 30 x-beams and 20
y-beams, you can type either:
SBC A320 I5 X30 Y20
or
sbc i5 x30 a320 y20
