Terminal Adapter
Sr=n Set S-Register
Values: r = 0, 2–5, 7, 10, 25, 32, 50-53; n varies
Default: None
Use to set the value of an S-register, where
r is the number of the S-register, and n is the
value you want to set. (For more information on S-Registers, see Chapter 6, T erminal
Adapter S-Registers .)
Sr? Read S-Register
Values: r = 0–5 (S1 is read only) , 7, 10, 25, 32, 50-53; n varies
Default: None
Use to read the value of an S-register, where
r is the number of the S-register. (For more
information on S-Registers, see Chapter 6, Terminal Adapter S-Registers .)
Vn Terse/Verbose Result Codes
Values: n = 0 or 1
Default: V1 (Verbose)
Use to control whether the TA’s result codes display as digits (terse) or as words
(verbose). (Use the
Q command to enable or disable the display of result codes.)
V0 Enable terse result codes.
V1 Enable verbose result codes.
Xn Connect Messages
Values: n = 0, 1, or 2
Default:
X2 (Enable all messages)
Use to select which result code messages the TA sends to the computer.
X0 Enables messages OK, CONNECT, RING, NO CARRIER, and ERROR (terse
result codes 0–4 ).
X1 Enables all messages except BUSY (terse result codes 0–5, 10–14, 17–19,
28, and 32 ). If a call is placed to a busy line, NO CARRIER displays.
X2 Enables all messages (terse result codes 0–5, 7, 10–14, 17–19, 28, and 32 ).
Z Reset to Stored Profile
Values: none
Default: none
Resets TA to its current power-up profile and clears the command buffer. The result is the
same as turning the TA off and on. When you type ATZ, the state of the
&W command
determines where default values originate. &W0 defaults come from the customized
configuration in NVRAM, and &W1 defaults come from the factory default configuration in
ROM. Because Z clears the command buffer, it must be the last command in a command
string; normally it is issued by itself: ATZ. Note that whereas the &F0 reset command
always restores the factory default profile, the Z reset command restores either the
factory default or the stored profile, depending on how the &W command is set.
