Description
0x1d lat_code --- 0 0xffffff R/W
Coded geodetic latitude 0: North
Pole, 0xffffff: South Pole
0x1e lon_code --- 0 0xffffff R/W
Coded geodetic longitude 0:
Greenwich Median, increasing in
eastern direction
0x1f msg_requeue_opt 1 1 1 R/W
NOT SUPPORTED - DO NOT
MODIFY
0x20 poll_response_timeout 5 2 30 R/W NOT SUPPORTED
0x21 ser_max_retries 0 0 255 R/W
Number of successive packet retries
without receiving valid ACK before
discarding packets
Additional notes: This parameter works in conjunction with parameter 0x22 (ser_pkt_timeout). It specifies the number
of attempts the modem will make to re-send a packet (to the application) that it does not receive a valid Link Level
Acknowledgement (LLACK) packet for. For example: The modem receives a modem-T message from the network
and ser_max_retries (0x21) is set to a value of 3. The modem will make its initial attempt to send this packet to the
application. If the application does not return a valid LLACK packet, the modem will wait X number of seconds
(specified by parameter 0x22) and then try to resend the packet. In this example, it would retry 3 times before
discarding the packet.
0x22 ser_pkt_timeout 3 1 30 R/W
Number of seconds modem waits for
ACK after sending last byte of a
packet before resending
Additional notes: As mentioned above, this parameter specifies the number of second the modem will wait between
retrying to send a packet to the application that it did not receive a valid LLACK packet for.
0x23 abort_response 0 0 1 R/W
Abort Response 0: do nothing, 1:
send abort report
0x24 abort_report --- --- --- W
Abort Report values of ncc_id,
polled, serv_type, or_ind, and info
bytes 0-5 for abort report
0x25 ops_mode 0 0 2 R/W NOT SUPPORTED
0x26 ob_flow_cntl 3 0 3 W
Sending packets/bytes to DTE:
0: deactivated DTR stops it
1: activated RTS stops it
2: either
3: no outbound flow control
0x27 ib_flow_cntl 3 0 3 W NOT SUPPORTED
0x28 DSR_treatment 0 0 1 W
0: Not enabled

queued in modem (Used with
parameter 0x26)

5: 9600, 6: 19200, 7: 38400, 8:
57600, 9: 76800, 10: 115200
Additional notes: This parameter can be used to modify the baud rate of the MTS port.
0x2a parity_bits 0 0 2 R/W DTE parity 0: none, 1: odd, 2: even
0x2b stop_bits 1 1 2 R/W DTE stop bits
0x2c data_bits 8 7 8 R/W DTE data bits
0x2d duplex 1 0 2 R/W
NOT SUPPORTED (MTS Port is full
duplex)
0x2e test_mode 0 0 4 R/W
Test Mode
0: normal operation
1: echo downlink data to DTE
2: echo uplink data to DTE
3: echo both to DTE
4: echo DTE to uplink as reservation
burst
0x2f pwr_down_mode 1 0 1 W
0: receiver power controlled by DTE
DTR signal
1: receiver power controlled by
rcvr_power parameter
Additional notes: When this parameter is set to 0 the modem will power down when DTR is deasserted.
0x30 active_set_id 1 0 1 R/W NOT SUPPORTED
