V.8 and V.8bis Operation Controls
Use this command to set the control parameters for early call negotiation through V.8
and V.8bis. +A8E may also be used as an action command to reinitiate V.8 or V.8 bis
if an earlier attempt to use either protocol has failed. (ITU-T Recommendation V.251
(02/98) standardized this command. However, the controller-based command set
only includes partial support for the standard.)
On-Hook: 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.
Off-Hook: 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.
The ATD and ATA commands behave as specified in V.250, and +A8n indications
are not generated by the modem.
For subparameter values <v8o>=6 and <v8a>=5, the +A8I indications are issued
during the course of the V.8 session to notify the DTE when the relevant V.8 signals
are received.
<v8o> enables or disables DCE-controlled V.8 origination negotiation.
<v8a> enables or disables DCE-controlled V.8 answer negotiation.
<v8b> disables V.8 negotiation or sets it to DCE controlled or DTE controlled
negotiation.
<a8cf> sets the V.8 CI signal call function to the value specified.
The valid range for this parameter is 0 to FF, with a default of 0xC1.
AT+A8E=<v8o>,<v8a>,<v8cf>,<v8b>
<v8o> Decimal number which enables/disables issuance of +A8x indications during
<v8a> Decimal number which enables/disables issuance of +A8x indications during
<v8b> Decimal number which enables/disables V.8bis negotiation.
<v8cf> Set the V.8 CI signal call function to the hexadecimal octet XY.
+A8E?
+A8E=? Reports supported parameter values.
This command does not work with parallel, USB, PCI, PCIe.
