REG11: Retransmission Count [default value: 32H]
•
Sets the maximum
number of packet retransmission
attempts. Valid values are 000
to 255.
•
When retransmission exceeds the
retransmission count
(
retransmission count
plus
one), the modem outputs an error response to the terminal equipment.
REG12: Roaming Threshold [default value: 50H]
•
At the time to set the
frequency roaming
(
REG19:bit 2
is 1), set the
receiving
strength threshold of the radio beacon
which starts scanning frequency.
•
Set the value of the desired radio beacon strength threshold represented in dBm
excluding the minus sign, e.g., set to “080” to search the next master station when the
radio beacon strength becomes below –80 dBm.
REG13: Buffer Data Timeout [default value: 1EH]
•
Valid values are 000 to 255, representing seconds in 1 s increments.
REG14: Command Input Timeout [default value: 32H]
•
Sets the character
input timeout interval for command input
. It is used as the
timeout between the command header and the character following it and between
each character of the command.
•
At the timeout, the modem operation transits from command-input-state to data-
wait-state
.
•
Valid values are 000 to 255, representing tenths of seconds in 0.1 second increments.
(Set an integer value equal to ten times the number of seconds desired.)
•
A setting of 000 disables this timeout function
REG15: Command Recognition Interval [default value: 00H]
•
When a message data contains a
command header
character (in case of binary data
or data in two-byte Chinese characters), data following the command header
character will be interpreted as a command, the message does not transmit properly.
•
Sets the necessary vacant duration
time interval
to discriminate between ordinary
data character and a
command header
character. Input a command after a longer
interval than
time interval
setting.
•
Valid values are 0.1 to 25.4 sec., representing tenths of seconds in 0.1 second
increments. (Set an integer value equal to ten times the number of seconds desired.)
•
When set to 000, the
command header
is recognized at any time, and when set to
255, all command header character are ignored.
