Register description
The register value could be updated using the ATSn=m<cr> command and
displayed using ATSn?<cr> command.
At power-up, the previous transceiver configuration is restored from E2PROM
(non volatile) to RAM. The registers are located in RAM registers, any
modification is performed on RAM registers: To save current register
configurations, it is necessary to use the AT&W<cr> command. If not, the
updated parameters are lost in case of power shortage.
The registers are shared in 2 types: read only (R) or read/write (R/W)
It is mandatory that the Master modem and the Slave modem have exactly
the same registers configuration in term of : hopping table (S200), start
channel (S201), channel type (S202), serial parameters (S210, S211, S212,
S213), handshake (S216), protocol (S220) and packet retries (S221).
It is recommended to have the same RF OUT level (S231).
