Note on Unsolicited Point Addresses

Unsolicited addresses are referenced with a U followed by a hex offset of 4 digits including leading zeros. For example, U012C is a valid address, while U12C is not. The valid range for the offset is 0000-7FFF. For example, U7FFF is a valid address, while U8000 is not.

For all device types except the Fixed Buffer, the address may be entered in any combination of upper and lower case letters. For Fixed Buffer devices, the address must be configured with all uppercase characters or digits.
