+FAA=1 The DCE can answer and automatically determine whether to answer as a facsimile
DCE or as a data modem.

+FAA?
+FAA=?
+FAP=<sub>,<sep>,<pwd>—Address and Polling Capabilities
+FAP=<sub>,<sep>,<pwd> is used by DTE to indicate its capability regarding subaddressing, selective
polling, and passwords. It is also used by DTE to indicate its willingness to accept this information. The
remote station is notified of these capabilities in the DIS or DTC frames: bit 47 for SEP, bit 49 for SUB, and
bit 50 for PWD.
A value of 0 indicates capability is disabled, and a value of 1 indicates it is enabled; the default value is
0,0,0. The DCE receiving this information ignores disabled subparameter frames. If a subparameter is
enabled, the DCE reports the received frame using the +FPA: report command.
Result codes:
• OK if <sub> = 0,1 and <sep> = 0,1 and <pwd> = 0, 1.
ERROR if <sub> ≠ 0, 1 and <sep> ≠ 0, 1 and <pwd> ≠ 0, 1.

+FBS?—DCE Buffer Size Reporting (Read Only)
This command allows the DCE to report its transmit and receive data buffer size. The buffer size is
reported in hexadecimal and represented in octets. The first value represents the transmit buffer size (tbs),
followed by the receive buffer size (rbs). Default value is 0800,0800. The range for tbs and rbs is 0000-
FFFF.
Result codes:
• <tbs>,<rbs>
• This command always yields an OK result code.
