ATS91=<bitmask> Bit Value Result
0 1 Use reverse SDLC establishment (SNRM sent by answerer and not by
caller). Mandatory for POS.
1 2 Poll on each SDLC frame. Required by some POS terminals.
ATS92=<n> SDLC Address A (default 0x30)
ATS128 S-register 128 is a read-only register. Reading this register allows to retrieve information
on the current (last) incoming call. It returns a message in the following format:
;<calling party number>;<destination_address>. If calling party or destination sub-
addresses are present, they are separated by a slash "/" from the called party number or
the destination address. For example, the calling party number 800, calling party sub-
address 900, destination address 400, destination sub-address 500 are presented as:
;800/900;400/500.
ATS172=<bitmask> Bit Value Result
0 1 Enable transmission and reception of empty frames.
1 2 Enable "multimoding", i.e. a trailing byte (modulation tag) in every
frame specifies which modulation has to be used to send this frame or at
which modulation it was received. Valid modulation tags are 0x27 for
V.23 HDX off hook and 0x28 for V.23 HDX on hook.
2 4 Shield empty frames. This mode enables a tty application to send and
receive empty frames. Since a frame with a length of 1 byte is invalid in
the V.23 SMS and V.23 Caller ID protocol, it is used to carry the
information that an empty frame occurred and which modulation was
detected. The data byte in a real 1 byte frame is replaced by a unique
value 0xff. A single byte frame 0x27 indicates or issues an empty frame
in V.23 HDX off hook. A single byte frame 0x28 indicates or issues an
empty frame in V.23 HDX on hook.
