Example 2 - Dialling other modems at 19,200 bps (V.34 or V.FC)
B Command Setting: B18
Terminal Speed: 57,600 bps
Flow Control: On (&K3 for RTS/CTS flow control)
You may use this arrangement when dialling online information services or bulletin boards. With
these settings, you modem will attempt to connect at 19,200 bps, but may change the line speed
if the quality of the telephone line does not support this speed.
Example 3 - Dialling information services at 1200 bps (or V.22)
B Command Setting: B6
Terminal Speed: 38400 bps
Flow Control: On (&K3 for RTS/CTS flow control)
Some information services do not provide connections higher than 1200 bps; these settings allow
you to connect to such services. Problems may also occur if error correction is switched on; if
the information service does not support V.42 or MNP, issue the \N0 command before dialling.
V.32bis Modem Typical Settings
Here are some example settings that may be relevant to the way in which you wish to operate
your modem with V.32bis.
Example 1 - Dialling other modems at the highest possible V.32bis speed
B Command Setting: B0
Terminal Speed: 38,400 bps
Flow Control: On (&K3 for RTS/CTS flow control)
Use this arrangement when dialling online information services or bulletin boards. With these
settings, your modem will attempt to connect at any speed from 14,400 bps to 1200 bps. These
are the default settings of your modem.
Example 2 - Dialling other modems at 14,400 bps (or V.32bis)
B Command Setting: B15
Terminal Speed: 38,400 bps
Flow Control: On (&K3 for RTS/CTS flow control)
You may use this arrangement when dialling online information services or bulletin boards. With
these settings, your modem will attempt to connect at any speed from 14,400 bps to 1200 bps.
Because V.32bis operation is not suitable on poor-quality telephone lines, we recommend you
use these settings with caution; if you have trouble connecting to another modem using V.32bis,
revert to the settings shown in Example 1.
