SYNC DATA AT&M1 Modem accepts asynchronous command in command state, but exchanges data synchronously in data state. SYNC AT&M3 Modem accepts synchronous command (V.25bis) and exchanges data synchronously with a remote modem. You can always use panel operation to control and configure the modem and use manual dial and answer to operate the modem. DIAL FROM SYNCHRONOUS MODE 1) Dial from terminal using asynchronous command Set &M1 and use asynchronous AT command to dial the number. After the modem is connected, the modem will enter synchronous operation. 2) Dial through the computer using V.25bis commands Some communication software on the synchronous computer can dial using V.25bis synchronous commands. In this case, set &M3 and *I1 and modem will accept the synchronous V.25bis dialing command and make a synchronous connection. 3) Using DTR to dial a stored number in synchronous mode Store the telephone number from the front panel STORE NUMBER menu or by asynchronous command &Zn=. Use DEFAULT DIAL parameter menu or *Dn command to select the default dial pointer. Set &D1 and either &M1 or &M3, then raise DTR from your terminal or communication software. The modem will dial the default stored number. After the modem is connected, the modem will enter synchronous operation. On the U-1496E, with S35 bit 4 set, pressing DATA/VOICE switch will also cause dialing of the default number. 4) Dial from panel This is available only with U-1496 or U-1496R's LCD panel. Set modem to synchronous mode, then select DIAL MEMORY or DIAL NUMBER to dial out the number you want. After the modem is connected, the modem will enter synchronous operation. 5) Manual dial Set modem to synchronous mode (&M1 or &M3), then dial a number from a telephone set. When you hear the answer tone, type ATD (if set &M1) or press `O' on the IDLE SCREEN menu from the panel. On the U-1496E, press the VOICE/DATA switch with the ANS/ORG switch set to ORG. The modem will go into synchronous operation after connection. AUTO-ANSWER FROM SYNCHRONOUS MODE Set the modem to synchronous mode. Just as in the asynchronous setup, set S-Register S0 equal the number of rings to auto-answer. This can be set from the terminal (if set &M1) using the asynchronous AT command, or select the STATUS REGISTER menu to change the S0 value.

SYNC DATA
AT&M1 Modem accepts asynchronous command in command state, but
exchanges data synchronously in data state.
SYNC
AT&M3 Modem accepts synchronous command (V.25bis) and exchanges data
synchronously with a remote modem.
You can always use panel operation to control and configure the modem and use manual dial
and answer to operate the modem.
DIAL FROM SYNCHRONOUS MODE
1)
Dial from terminal using asynchronous command
Set &M1 and use asynchronous AT command to dial the number. After the modem is connected,
the modem will enter synchronous operation.
2)
Dial through the computer using V.25bis commands
Some communication software on the synchronous computer can dial using V.25bis
synchronous commands. In this case, set &M3 and *I1 and modem will accept the synchronous
V.25bis dialing command and make a synchronous connection.
3)
Using DTR to dial a stored number in synchronous mode
Store the telephone number from the front panel STORE NUMBER menu or by asynchronous
command &Zn=. Use DEFAULT DIAL parameter menu or *Dn command to select the default
dial pointer. Set &D1 and either &M1 or &M3, then raise DTR from your terminal or
communication software. The modem will dial the default stored number. After the modem is
connected, the modem will enter synchronous operation.
On the U-1496E, with S35 bit 4 set, pressing DATA/VOICE switch will also cause dialing of the
default number.
4)
Dial from panel
This is available only with U-1496 or U-1496R's LCD panel. Set modem to synchronous mode,
then select DIAL MEMORY or DIAL NUMBER to dial out the number you want. After the modem
is connected, the modem will enter synchronous operation.
5)
Manual dial
Set modem to synchronous mode (&M1 or &M3), then dial a number from a telephone set.
When you hear the answer tone, type ATD (if set &M1) or press `O' on the IDLE SCREEN menu
from the panel. On the U-1496E, press the VOICE/DATA switch with the ANS/ORG switch set to
ORG. The modem will go into synchronous operation after connection.
AUTO-ANSWER FROM SYNCHRONOUS MODE
Set the modem to synchronous mode. Just as in the asynchronous setup, set S-Register S0
equal the number of rings to auto-answer. This can be set from the terminal (if set &M1) using
the asynchronous AT command, or select the STATUS REGISTER menu to change the S0
value.
