communicates with the
COM port) is online.
Close all programs that
communicate with COM port.
The response message
format or value is
different than
expected.
The response message

Request Commands
response does not match
the master command.

watched in the XtraWare
variable watch-window

longer open), message
response type is changed
to 3 (m=3) and the
message format holds the
variable value as well.
To delete a variable from the
watch list, set XtraWare to

desired variable(s) and return
to Offline mode. If XtraWare is
closed, rerun the program and
go Online and then Offline.
