Function and Description
The V command changes the format in which result codes are displayed.
V0
V1
The X command controls detection of a busy signal or dial tone when the
modem is dialing. The X command also limits the result codes the modem may
return when dialing. The operation of the X command is configurable for
operation in different countries.
X0
X1
X2
X3
X4
The @ and W dial modifiers are not affected by the X command. The @ dial
modifier may return the result codes 8 (NO ANSWER) or 7 (BUSY) each time it
appears in the dial string. The W dial modifier may return the result codes 6
(NO DIALTONE) or 7 (BUSY) each time it appears in the dial string.
The &Z0=x command saves a dialing string in the modem's nonvolatile memory
(EEPROM). The value of X may be up to 36 characters long and may contain
any dialing digits or modifiers, except the S=n modifier. Characters that are
neither dialing digits or dial modifiers are ignored and not stored. If the modem
does not feature nonvolatile memory, an ERROR result code is returned. The
command may be issued in one of three different ways:
&Z<dial string>
&Z=<dial string>
&Z0=<dial string>
All result codes are displayed as numbers.
All result codes are displayed as words (verbose form). This
value is the default value for North America.
Neither a busy signal nor a dial tone is detected. When a
telephone line connection is made, the result code does not
indicate the telephone line data rate.
Neither a busy signal nor a dial tone is detected. When a
telephone line connection is made, the result code indicates
the telephone line data rate.
A busy signal is not detected; however, a dial tone is
detected. When a telephone line connection is made, the
result code indicates the telephone line data rate.
Busy signal is detected; however, a dial tone is not
detected. When a telephone line connection is made, the
result code indicates the telephone line data rate.
Both a busy signal and a dial tone are detected. When a
telephone line connection is made, the result code indicates
the telephone line data rate. This value is the default value
