8.3.7 Memory Q & A
Q: Can a user create a program too large to fit on the CPU: drive (>100k) and
have it run from the CRD: drive (CF card)
A: The program does not run from the CF card. However, a very large program
(too large to fit on the CPU: drive) can be compiled into CR1000 main memory
from the card if the binary form of the compiled program does not exceed the
available main memory (p. 330).
8.4 Telecommunications and Data Retrieval
Telecommunications, in the context of CR1000 operation, is the movement of
information between the CR1000 and another computing device, usually a PC.
The information can be programs, data, files, or control commands.
Telecommunications systems require three principal components: hardware,
carrier signal, and protocol. For example, a common way to communicate with
the CR1000 is with PC200W software by way of a PC COM port. In this example,
