Telelocator 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.[1][2]

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.[3]

TAP was also known as IXO protocol.[4] Originally, devices like the IXO Device were used to send Alphanumeric Pages using TAP. Later, Motorola would create a similar device called the AlphaMate.

TAP Communication Protocol[edit]

The standard protocol is ASCII with XON/XOFF flow control, using a 10-bit code (1 start bit, 7 data bits, even parity, 1 stop bit). No echo shall be employed in full duplex mode.[5]
