Communications Procedure Section 6-1
Command Chart The commands listed in the chart below can be used for host link communica-
tions with the CQM1/CPM1/CPM1A/SRM1. These commands are all sent
from the host computer to the PC.
6-1 Communications Procedure
Host link communications are executed by means an exchange of commands
and responses between the host computer and the PC.
With the CQM1, there are two communications methods that can be used.
One is the normal method, in which commands are issued from the host com-
puter to the PC. The other method allows commands to be issued from the
PC to the host computer.
