Synchronous Mode Operation
This chapter introduces you to the use of the U-336R/RE for
synchronous operation. The modem can be used as a synchronous
modem when it is connected to a synchronous computer or
terminal. It is of course necessary to make sure that the remote
modem and system are also set to synchronous mode. Synchronous
operation applies to all of the non-FSK modes the modem is
supplied with. Before synchronous transfers are started, some initial
settings should be made.
V.25bis Command Set
To enable V.25bis commands use the AT*I1 command.
For synchronous applications, the modem is permanently set in
normal situations for use with one application. Save the desired
settings in the power-on profile, and the modem will be initialized
to synchronous mode, (&M3) with V.25bis command enabled,
(*I1) when powered on.
A special command RST is provided to get the modem back to
asynchronous AT command mode from V.25bis mode. You can
enter this RST command in either synchronous or asynchronous
V.25bis mode.
