12.1 DISCOVERYSTRING Connection Modifier

This RP defines a new IOCTL for performing device discovery for wireless devices. See RP1210_LOCTL  below for details. The output of that mechanism is a string value which may be used as a connection string modifier to allow the client application to specify a particular device for connection. The form of the modifier is:

G13956545

The <value> is the string returned by the new device discovery IOCTL and is VDA vendor defined. It should be a valid ASCII string with no embedded nulls, "=" or "," characters which would interfere with normal connection string modifiers such as Baud, SJW, or any others defined in RP 1210D, RP1210_CLIENTCONNECT () . An example connection string might be:

The discovery string is intended to be an instance of a device to support having multiple devices in range with wireless. The discovery string is a connection string modifier and does not replace the Device ID. The Device ID from the Vendor INI file is still used in all subsequent function calls.
