\T Automatic Transmit Control
Enables the inter-character time-out data forwarding operation of the packet assembler in online mode.

S-Register 50, the data in the packet buffer is transmitted. The time-out value is specified in tenths of
seconds; the default is 20 (2 seconds). Refer to Chapter 4, Broadcast and Multicast Operations, Data
forwarding, for more information, and Chapter 8, Application Programming, Binary data transfer, for
more information.

Table F-4. Commands beginning with asterisk (*)
*A Select Server Type
Specifies the type of server to be used and can be issued at any time, stopping the current server process
and starting the requested process. Only one server type can be active at a given time.
The current server option can be viewed by inspecting the *An option in the modem profile by use of the
AT&V command.
Format:
AT*A0 No server process. This is the default setting and is appropriate if the attached
device always operates in client mode, for example, always originating connection
requests with an ATDT command.
NOTE:
This command must also be used as an intermediate step when switching server
types.
AT*A1 Selects TCP server process. This allows the modem to accept incoming TCP
connection requests when in command mode and is consistent with earlier versions
of the modem software. Refer to Chapter 5, DART Supported Protocols, Basic
UDP, for more information.
AT*A2 Selects UDP server process. This allows the modem to accept incoming UDP data
packets when in command mode. Refer to Chapter 5, DART Supported Protocols,
UDP Server characteristics for more information.
Result codes:
OK Requested server mode is set.
ERROR Invalid argument.
