1. S̲C̲O̲P̲E̲
The purpose of this document is to describe the functions
performed by the PC LTU Driver.
1.1 I̲N̲T̲R̲O̲D̲U̲C̲T̲I̲O̲N̲
The Driver is a single CR80 Process that interfaces
a LTU to the Application Process.
The Application Process sends commands to the Driver
and answers are sent back to the Application Process.
A PC LTU Driver Process can drive one LTU, the LTU
being either a CAMPS/SCARS LTU or a CCIS LTU, so two
PC LTU Driver Processes are required to drive both
the CAMPS/SCARS LTU and the CCIS LTU. The two processes
share the same program area.
