3.4 Example of Communication Program
The communication program on the computer should be written to handle such processes as
described in "3.3. Actual Communications (Page 55)". In this section, an example of communica-
tion program is provided for reference.
3.4.1 Communication Program
A sample program for data communication to be installed to the computer is provided on the page
after the next page. BASIC is used as a programming language.
In this example, the Com mode parameter on the LM should be set to “NIDEK”. Because commu-
