Command: +FRS  Receive 
Silence 
 
Description: 
 
This command causes the modem to listen and report an OK result code 
when silence has been detected on the line for the specified period of time. 
This command will terminate when the required period of silence is detected 
or when the DTE sends the modem another character other than XON or 
XOFF, which is discarded. In either event, the OK result code is returned. 
 
 
 
 
This command is aborted if any character is received from the DTE after 
receipt of the command but before the time delay elapses. In this case, the 
modem discards the aborting character and issues an OK result code. 
Defined Values:  
<time> Decimal number from 0 (default) to 255 which specifies the length of 
time in 10-ms intervals to delay before responding with the OK result code 
after detecting silence on the line. 
Result Codes:   
OK Reported when silence has been present on the line for the specified 
amount of time or when the DTE sends the modem a character other than 
XON or XOFF. 
 
 
ERROR <value> is invalid or this command is issued while the modem is on-
hook. 
Reporting Supported Range of Parameter Values: 
  
Command: 
+FRS=? 
 
 
Response: +FRS: <time> range 
 
 
Example: +FRS: 0-255 
 
 
Command: +FTM  Transmit 
Facsimile 
Description: 
 
This command causes the modem to transmit data using the modulation 
defined below. When a valid <mod> value is entered, the modem transmits 
the proper training sequence in the selected mode, followed by constant 1 bits 
until data is received from the DTE. The modem also returns the CONNECT 
result code at the beginning of the training sequence.  
Defined Values:  
<mod> Decimal number corresponding to the selected modulation mode and 
data rates shown in Table 3-2.
