MOD_RESET_STATE
state 1
state 2
This transition show 2 transitory states.
During transitory states 1 and 2, the DTE can't send data. If it has to, it must put DTE_UART_STATE
up first.
During transitory state 1, the DTE can receive data and the DCE can send data: there's no problem
for DCE to emit.
During transitory state 2, the DCE can't send data and the DTE can't receive data. So if the DCE
wants to emit, it must put MOD_FLOW_STATE up first.
The state 2 can be long.
