Telocator Alphanumeric Protocol
Telocator Alphanumeric Protocol (TAP) is an industry-standard protocol for sending short messages via a land-line modem to a provider of pager and/or SMS services, for onward transmission to pagers and mobile phones.
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.
