Summary:

When I call IODeviceInfo in Mode 10 from a remote client to obtain the status of the I/O Device, it returns an empty string. Calling this same function from the I/O Server works correctly. What am I doing wrong?

Solution:

To obtain the status of an I/O Device from a remote client's perspective, you need to call the IODeviceInfo function in mode 3. For example, if trying to obtain the status of an I/O Device called IODev in a Cluster called Cluster1, your Cicode call would be as follows: IODeviceInfo("IODev",3,"Cluster1")
