When starting update mode over the network, the
serially connected device is informed of the access
with a short message.
The update mode is protected with a timeout of 30s. If no
data are transmitted within this time, the LAN-Modem
automatically resumes normal operating mode.
If updating over the network is automated in any way,
you must ensure a pause of at least 0.5 seconds between
s e n d i n g o f o t h e „ U “ a n d t h e s t a r t o f f i r m w a r e
transmission. The LAN-Modem needs this time to delete
the internal serial receive buffer when switching over to
update mode.
