MTPSR1-202ST
Values: r = 0, 2–5, 7, 10, 25, 32, 50-53; n varies
Default: None
Description: Use the
Sr=n
command to set the value of an S-register, where

is the number of
the S-register, and
n
is the value you want to set. See “S-Registers” in this chapter for further infor-
mation.
Command:
Sr?
Function: Read S-Register
Values: r = 0, 2–5, 7, 10, 25, 32, 50-53; n varies
Default: None
Description: Use the
Sr?
command to read the value of an S-register, where
r
is the number of
the S-register. See “S-Registers” in this chapter for further information.
Command:
Vn
Function: Terse/Verbose Result Codes
Values: n = 0 or 1
Default:
V1
(Verbose)
Description: Use the
V
command to control whether the ProxyServer’s result codes are displayed
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.
Command:
Xn
Function: Connect Messages
Values: n = 0, 1, or 2
Default:
X2
(Enable all messages)
Description: Use the
X
command to select which result code messages the ProxyServer sends to
the computer.
X0
Enable the messages
OK, CONNECT, RING, NO CARRIER,
and
ERROR
(terse
result codes
0–4
).
X1
Enable 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, the message
NO CARRIER
is displayed.
X2
Enable all messages (terse result codes
0–5, 7, 10–14, 17–19, 28,
and
32
).
Command:
Zn
Function: Reset to Stored Profile
Values: none
Default: none
Description: The
Z
command resets the ProxyServer to its current power-up profile and clears the
command buffer. The result is the same as turning the modem off and on. When you type ATZ, the
state of the
&W
command determines where the default values originate.
&W0
defaults come from
the customized configuration in NVRAM, and
&W1
defaults come from the factory default configura-
tion 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
com-
mand is set.
Command:
&Cn
Function: DCD Control
Values: n = 0, 1, or 2
Default:
&C1
(DCD normal)
Description: The
&C
command controls the behavior of the DCD (Data Carrier Detect) signal (pin
8 on the RS232E/V.24 interface). Normally, DCD goes high when the ProxyServer establishes a
connection, and drops when the connection is lost. However, you can also force DCD to remain high
at all times, or to remain high except for a brief drop following a disconnect.
&C0
DCD is forced high at all times.
