COURIER HIGH SPEED MODEMS
It is a good idea to find out if the remote modem is MNP-
compatible. Some public network services, for example, are not.
If the remote modem doesn't have MNP capability, it may
misinterpret the error control request and block a successful
connection.
If you know the remote modem doesn't support
MNP, disable MNP handshaking by setting Register 527 to 16.
The modem still connects with V.42-compatible modems.
PLACING CALLS
Dial
(D)
The commands discussed in this section are used in the follow-
ing operations:
Dialing D (0-9
#*,;!PT W @R), DSn
Redialing
A/, A>, >
Canceling
dialing <any key>
When the Dial command is issued the modem goes off
hook-the equivalent of picking up your phone-then enters
Originate mode and dials the number sequence that follows.
The modem also executes any other commands or options
included in the command line.
The
command string may include up to 40 characters. The
modem counts, but ignores punctuation characters such as
parentheses and hyphens. It does not count spaces, the AT pre-
fix or the Carriage Return (Enter key) required to execute the
command.
The following command example instructs the modem to stop
the display of commands (EO, turn off the local echo), turn off
the speaker (MO), and dial (D) the phone number (1234567)
using Touch-Tone dialing (T). The spaces shown are ignored by
the modem and are only included here for readability.
AT EO MO OT 1234567 <Enter>
Cancel Dialing
To cancel Dial-command execution, press <any key>. If you
inadvertently hit a key on the keyboard while the modem is
dialing,
the call is canceled. If this occurs, type the A/ command
explained under Redialing later in this chapter.
