The following table shows the +FRS parameters.
Table 3-32: +FRS Parameters
Description
The duration of the silence, in 10 millisecond intervals.
0-255 Number of milliseconds.
Example
At+fclass=1
OK
Atd035658584
CONNECT 9600
OK
At+frs=50
OK
//The H24 sends the OK after silence for 10*50 milliseconds
+FTM, Transmit Data
This command causes the H24 to transmit data to the remote party using the modulation selected
in . The H24 sends the data stream received from the terminal without any framing.
Transmission Using the Transparent Data Command
The DLE character, (0x10), is used as a special character to precede command characters. The
character pairs are used to convey commands or status information between
the terminal and the H24.
• Terminal to H24 streams (Encoding)
–When the terminal needs to send a character in the data stream, it sends two
sequential characters to the H24.
–When the terminal needs to send two sequential characters in the data stream, it
sends the characters instead.
–When the terminal sends the terminator sequence , the data stream is
terminated.
• H24 to terminal streams (Decoding):
–The terminal decodes the input stream and removes all character pairs beginning with
.
–The terminal recognizes as the data stream terminator.
–The terminal recognizes and replaces by a single in the data stream.
–The terminal recognizes and replaces by a single in the data
stream.
When the H24 receives the +FTM command, it immediately returns an OK result code. When the
terminal receives the OK from the H24, it can start sending the data stream using the transparent
data command encoding. When the H24 decodes the terminating sequence, it returns a
CONNECT.
