+FAE=n - Data/Fax Auto Answer
+FAE=n allows the DTE to either restrict answering to class 1, or to automatically detect whether the calling station is a fax
class 1 modem or data modem, and answer accordingly.
Parameters: n = 0 or 1
Command options:
n = 0 Disable data/fax auto answer mode. The modem answers as a fax modem only. (Default.)
n = 1 Enable data/fax auto answer mode. The modem answers as a fax or data modem.
After a data (not fax) connection is achieved (indicated by the DATA result code), the DTE must issue an ATO command to
cause the modem to go on-line.
+FTS=n - Stop Transmission and Wait
+FTS=n causes the modem to terminate a transmission and wait for n 10-ms intervals before responding with the OK result
code. An ERROR response code results if this command is issued while the modem is on-hook.
+FRS=n - Receive Silence
+FRS=n causes the modem to report back to the DTE with an OK result code after n 10 ms-intervals of silence have been
detected on the line. This command is aborted if any character is received from the DTE. The modem discards the aborting
character and issues an OK result code. An ERROR response code results if this command is issued while the modem is
on-hook.
