In the UK, the # button is used heavily for network features, usually with the meaning of "cancel an instruction" or "terminate an instruction string". For example, the command to divert is typically *21*number# where # is the terminator. The command to cancel diversion is #21#, where the first # indicates cancel and the second is the terminator. The command *#21# means "interrogate diversion status". Many other network features use the # button in a similar way. -- Bill Lyons - [email protected] / [email protected] This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
