V.8/V.8bis Commands
+A8E - V.8 and V.8bis Operation Controls
This command is defined for two conditions: as a parameter while the modem is
on-hook, and as an action command while the modem is off-hook. If enabled, V.8
negotiation does not preclude simultaneous implementation of other negotiation
means (e.g., V.8bis, V.18, V.32bis Annex A).
This command is a compound parameter if issued while the modem is on-hook,
used to precondition V.8 and V.8bis originating and answering operation. It is
issued by the DTE before the Dial (D) or Answer (A) command, regardless of the
state of the +FCLASS parameter.
This command is an action command if issued while the modem is off-hook, to
(re)start V.8 or V.8bis negotiation. For example, if initial V.8 negotiation failed, but
subsequent T.30 negotiation indicated V.8 capability, this command may be used
to initiate V.8 negotiation.
