The AT (
ttyate

them according to the Hayes AT Convention.
The AT Hayes emulator has two different state:
1.
Command Mode

Data Mode
In the
Command Mode,
the characters that are received on the serial port are analyzed and when a
valid AT command is recognized, it is interpreted and execute locally.
In the
