Scanning for a Remote Device in the Wireless Network

ScanRemoteDevices, 0x80
When called, the system scans for remote 750-644 I/O modules or Bluetooth
SPP devices. The scanning process is asynchronous, i.e. the results are not
immediately available. As long as the scan runs, the wireless module is not
available for any other function. Functions that do not use the wireless module are
carried out normally. When the scan concludes, devices found are entered in a list
from which they can be individually queried with the command
"GetRemoteDeviceMacID". The complete CoD for the 750-644 I/O module is
0x0020f8 (hexadecimal).
To limit the scan to certain devices, a Class-of-Device (CoD) can be indicated. If
a CoD not equal to 0 is used, only those devices are found that have this exact
CoD. If CoD = 0 is used, all 750-644 I/O modules and Bluetooth
the environment are scanned.
