MDhh
Default power-up mode for the serial port: When the RLXIC-SG modem is power-
cycled, the serial port enters the mode specified by this command after 5
seconds. On startup, typing ATMD0 within 5 seconds changes the mode to
normal (AT command) mode. See also S53 to set the port for UDP or TCP.
S82=n
Enables UDP auto answer (half-open) mode.
ƒ
n=0 : Normal mode
ƒ
n=2 : Enable UDP auto answer mode.
S83=n
Set or query UDP auto answer idle time-out. If no data is sent or received before
the time-out occurs, the current UDP session will be terminated. While a session
is active, packets from other IP addresses will be discarded (unless *UALL is
set).
ƒ
n=0 : No idle time-out (Default).
ƒ
n=1 - 255 : Time-out in seconds.
*DU=n
The dial command always uses UDP, even when using ATDT.
ƒ
n=0 : Dial using the means specified (default).
ƒ
n=1 : Dial UDP always, even when using ATDT.
Note: When this parameter is set you cannot establish a TCP PAD connection.
*UALL=n
Accepts UDP packets from any IP address when a UDP session is active. If
there is no UDP session active, an incoming UDP packet will be treated
according to the UDP auto answer and AIP settings.
ƒ
n=0 : No effect (Default).
ƒ
n=1 : Accept UDP data from all IP addresses when in a UDP session.
*UDPLAST=n
Note: *UDPLAST does not change the S53 setting in NVRAM. If the modem is reset, the original
S53 setting will be restored from NVRAM.
If enabled, sets S53 to the last accepted IP address through UDP auto answer.
This can be used in conjunction with MD3 so that when there is no UDP session,
new Ethernet host data will cause a connection to be restored to the last IP
accepted through UDP auto answer.
ƒ
n=0 : Does not change S53 setting. (Default).
ƒ
n=1 : Set S53 to the last accepted IP.
