Online Connection Commands - Multitech MT5634HD16 User Manual

MT5634HD8/16 User Guide
&Qn Asynchronous Communications Mode
n = 0, 5, or 6
Default: &Q5
The &Qn command allows you to select the type of asynchronous communications mode for your
modem.
Note: These commands are the same as several of the \N n commands, described later in this chapter.
&Q0 selects asynchronous mode with data buffering. This is the same as \N0, non-error correction mode
with data buffering.
&Q5 selects error control with data buffering. This is the same as \N3, V.42/MNP auto-reliable mode.
&Q6 selects asynchronous mode with data buffering. This is the same as \N0, non-error correction mode
with data buffering.
%B View Numbers in Blacklist
If blacklisting is in effect, this command displays the numbers for which the last call attempted in the
previous two hours failed. In countries that do not require blacklisting, the ERROR result code appears.

Online Connection Commands

The following commands control the conditions of the online connection.
Bn Answer Tone
n = 0, 1, 2, 3, 15, or 16
Default: B1 and B16
The B command selects the frequency the modem uses for its answer tone. (The answer tone is the tone
transmitted by the receiving modem to the calling modem, thus initiating the handshake between the two
modems.) At higher speeds (2400 bps and above) there is no conflict, because all protocols use the Bell
frequency of 2225 Hz. Lower speeds require different frequencies.
B0 selects ITU-T V.22 mode when the modem is at 1200 bps.
B1 selects Bell 212A when the modem is at 1200 bps. This is a default.
B2 deselects the V.23 reverse channel.
B3 is identical to B2 in function. It also deselects the V.23 reverse channel.
B15 selects V.21 when the modem is at 300 bps.
B16 selects Bell 103J when the modem is at 300 bps. This is a default.
