<tcpTtcp> Transaction/TCP (T/TCP)
This parameter concerns T/TCP, an extension of TCP to provide a transaction-
oriented service.
T/TCP is described in RFC 1644. The value set with <tcpTtcp> enables or
disables T/TCP.
The parameter is global for the ME. Use of the power up value is
recommended.
0 Disable T/TCP extension. Default (This is a powerup default which is
not stored at power down).
1 Enable T/TCP extension.
<tcpWithUrc> URC Mode or Polling Mode for Internet Service Commands
This parameter enables or disables the presentation of the following URCs
related to Internet service commands: "^SISR" URC, "^SISW" URC and "^SIS"
URC for parameter <urcCause>=0 (Internet service events). "^SIS" URCs with
<urcCause>=1 or 2 used to indicate incoming Socket connections are always
enabled.
Parameter is global for the ME and non-volatile.
on Enable URCs related to Internet service commands.
Throughout the Chapter "Internet Service AT Commands" the mode is
also referred to as URC mode. Default (This is factory default value and
will be restored to 'x' with AT&F).
off Disable URCs related to Internet service commands.
This requires the host application to employ polling techniques when
using the Internet service AT commands: The host application is
responsible to retrieve all status information needed to control an
Internet session. The method is referred to as polling mode.
<succ> CIEV Call Status Indication
This parameter can be used to control the behavior of URC “+CIEV: call”. See
also AT+CIND, AT+CMER and Section 7.1, Call Status Information.
Parameter is global for all interfaces and will not be reset by AT&F.
restricted Default (This is a powerup default which is not stored at power
down). URC “+CIEV: call” will be issued only when a Call Status
transition ends in state “active” or “unknown”. This is the power
up default value of this parameter; it is not stored at power down.
(see Section 7.1, Call Status Information) for a call in the list of
active calls.
verbose URC “+CIEV: call” will be issued when any state transition
(including transitions beginning or ending in state “unknown”)
occurs in the list of active calls, or when a traffic channel is
established.
<sucs> SLCC Call Status Indication
This parameter can be used to control the behavior of URC “^SLCC”. See also
AT^SLCC and Section 7.1, Call Status Information.
The parameter is global for all interfaces and will not be reset by AT&F.
restricted URC “^SLCC” will be issued only when a Call Status transition
ends in state “active” or “unknown” (see Section 7.1, Call
Status Information) for a call in the list of active calls.
verbose Default (This is a powerup default which is not stored at power
down). URC “^SLCC” will be issued when any state transition
(including transitions beginning or ending in state “unknown”)
occurs in the list of active calls, or when a traffic channel is
established. Default.
