9.3. Example Session
The example below shows a typical session. The user determines the values of the U-registers.
transmit "AT+FCLASS=256<CR>"
waitfor "OK"
transmit "AT:UCA,0,12C,4E<CR>" ;Set SMS POS parameters
waitfor "OK"
transmit "ATD<phone number here>;<CR>"
waitfor "OK`x0d`x0a"
The ’;’ at the end of the dial string returns the modem to command mode after dialing. The modem will issue an
OK after dialing.
transmit "AT:UD1,3C<CR>"
waitfor "OK"
transmit "AT:UD2,3E8<CR>"
waitfor "OK"
transmit "AT+FRM=200<CR>"
The length of the timeout is dependent on the host called. Once the connection is made, the answer modem’s host
expects to receive a frame such as:
0x81 0x00 0x05 0x13 0xcd 0xaa 0xa4 0x00 0x4c
Followed by:
<DLE><ETX><CR><LF>OK<CR><LF>
Once a frame has been received, the receive modem becomes the transmit modem. The server returns a frame of
data to the terminal.
transmit "AT+FTM=202<CR>"; Use Protocol 2
waitfor "CONNECT `x0d`x0a"
Transmit a frame such as:
0x82 0x00 0x05 0x6c 0xea 0x50 0x6b 0x00 0x68
transmit "`x10`x03"
waitfor "OK`x0d`x0a"
; Set TxDelay = 600ms
; Wait 10 s for an answer.
; Go into data mode and wait for Originate modem
;Enable SMS POS mode
; Send <DLE><ETX> at the end of frame
