Vn Result Codes (Verbose/Terse)
n = 0 or 1
Default: V1
The V command controls whether the modem's result codes display as verbal ("verbose") or
digital ("terse") messages. For example, if no carrier signal is detected after dialing, the
result can be displayed either as NO CARRIER, or as the digit 3.
V0 (or V) displays the modem's result codes as digits.
V1 displays result codes as words.
Xn Result Codes and Call Progress Selection
n = 0–4
Default: X0
The X command selects which result codes the modem provides in command mode and
whether the modem uses "smart dialing" or "blind dialing". When it smart dials, the modem
listens for dial tones and busy signals and responds to them. When it blind dials, the
modem ignores the signals and relies on timing instead.
X0 causes the modem to blind dial. Instead of looking for a dial tone, it pauses for the time
set in register S6 and then dials regardless. Once a connection has been made, it sends
the Bell 103 basic code CONNECT to the terminal. It ignores any busy signals.
X1 causes the modem to blind dial, but in addition to the basic CONNECT code it provides
extended codes consisting of the word CONNECT and the speed of the connection:
CONNECT 2400, CONNECT 4800, CONNECT 9600, CONNECT 14400, CONNECT 19200,
CONNECT 28800, and so forth. In this mode, the modem does not recognize or respond to
dial tones or busy signals.
X2 causes the modem to wait for a dial tone before dialing. If it does not detect a dial tone
within the time set by S6, the modem sends a NO DIALTONE result code to the terminal. In
this mode, the modem provides extended result codes, but does not respond to busy
signals.
X3 causes the modem to blind dial, but also it looks for a busy signal, and if it detects one, it
sends a BUSY result code to the terminal. In this mode, the modem provides extended
result codes, but it does not respond to dial tones.
X4 causes the modem to look for a dial tone and a busy signal, and respond with NO
DIALTONE or BUSY, as appropriate. It also provides extended result codes. It is the most
useful setting for most datacomm programs.
&An Answerback
n = 0 or 1
Default: &A0
The &A command controls the MT2834MR6's answerback feature. Answerbacks are used
in some online realty applications and elsewhere as a security measure. The &A command
enables a modem to return a message to an identification request from another computer.
The default identification is MESSAGE NOT PROGRAMMED.
&A0 disables the answerback feature.
&A1 enables the modem to return a message to an inquiry.
