tions with I/O Memory Allocation, debug operations with actual serial
communications.
Display the [Serial Comm. Setting] window by [Status] | [Settings] |
[Serial Comm. Setting].
Set the communications settings for the Serial Communications Units
to be debugged to "Actual communications."
Confirm the Setup of the Unit for serial communications with I/O
Memory Allocation,
Caution
Enabling serial communications function of the CX-Simulator may affect the
operation of devices connected to the computer. When external devices are
not being used, do not enable the serial communications function. Unex-
pected operation of the external devices may cause an accident.
