asynchronous
transmission
A data transmission that is synchronized by a transmission start bit

commands must begin with the characters A
T and end with a
carriage return.
A
T pr
efix A prefix issued before every AT command (except A/ and +++)
which identifies the DTE’s data rate, parity, and character length.

rate when using A
T commands.
