How can I detect the feedback status of individual command successful or failed?
Article Number: 295 | Rating: Unrated | Last Updated: Fri, Jan 18, 2008 at 12:00 AM
Each command returns an error code once it is executed. If a command returns a value different of 0, this means that there was a problem during the command execution. The command error list can be found in the read data zone at the address you specified in mcm.port1.cmderrptr.
