COURIER HIGH SPEED MODEMS
NOTE: If you usually use the voice/ data switch for another
purpose, you can include the execute stored command option
832 = 9 in the stored command. However, the total number
of characters may not exceed 30.
4. Press the voice/ data switch when you want to connect with
the synchronous Host computer. You need not have your
communications software loaded at the time.
5. After the call, restore the modem to asynchronous oper-
ations by powering it off and on again.
ANSWERING
First configure the modem using the same guidelines described
for dialing out. To store a configuration string for the modem to
execute when you press the voice/ data switch, follow the steps
that begin on the previous page, with the following modifi-
cations:
• Insert SO = 1 in the stored command, Step 2. This sets
the modem to Auto Answer.
• Omit the Dial string shown in the same step (OT and
phone number).
If you don't wish to use a stored command and the voice/ data
switch, send the modem the appropriate configuration string,
ending with &ML The following adapts the dial-out command
example. Note again that all non-default settings follow the &F
command.
AT &F 50=1 &X1 &M1 <Enter>
The modem responds automatically to an incoming call, enters
synchronous mode and, in this case, because it is set to &Xl,
waits for synchronous timing signals from your DTE.
HANGING UP
The modem remains online until the remote modem disconnects
or your software causes the DTE to drop the Data Terminal
Ready signal (DTR). The Courier sends the NO CARRIER result
code if result codes are enabled, and returns to asynchronous
Command mode.
