Command State Options; Dialing From Synchronous Mode - ZyXEL Communications U-336R/RE User Manual

Command State Options

For synchronous data communication, there are two options you
can choose from to define how the modem will operate in the
command state.
SYNC

Dialing from Synchronous Mode

1. Dial from the terminal using asynchronous commands: Set
2. Dial through the computer using V.25bis commands: Some
3. Using DTR to dial a stored number in synchronous mode:
32 Synchronous Mode Operation
AT&M1
AT&M3
&M1 and use asynchronous AT commands to dial the number.
Once the modem is connected, the modem will enter
synchronous operation.
communication software packages on synchronous computers
can dial using V.25bis synchronous commands. In this case, set
&M3 and *I1 and the modem will accept V.25bis commands
and make a synchronous connection.
Store the telephone number by the asynchronous command
&Zn=. Use the 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.
The modem accepts asynchronous
commands in command state, but
exchanges data synchronously in data
state.
The modem accepts synchronous
command (V.25bis) and exchanges
data synchronously with a remote
modem.
