Telocator Alphanumeric Protocol (TAP) is a protocol for submitting requests to a cellular or pager service as a numeric or alphanumeric message.
This protocol is used to send SMS/text alerts to a cell phone or a pager.
TAP, initially known as Motorola Page Entry (PET) was adopted in September 1988, by the Personal Communication Industry Association. TAP defines an industry standard for sending alphanumeric messages to pagers.
TAP was also known as IXO protocol. Originally, devices like the IXO Device were used to send Alphanumeric Pages using TAP. Later, Motorola would create a similar device called the AlphaMate.
