- ---help---
- If you own a Texas Instruments graphing calculator and use a
- parallel link cable, then you might be interested in this driver.
-
- If you enable this driver, you will be able to communicate with
- your calculator through a set of device nodes under /dev. The
- main advantage of this driver is that you don't have to be root
- to use this precise link cable (depending on the permissions on
- the device nodes, though).
-
- To compile this driver as a module, choose M here: the
- module will be called tipar.
-
- If you don't know what a parallel link cable is or what a Texas
- Instruments graphing calculator is, then you probably don't need this
- driver.
