Terminal Adapter AT Commands & S-Registers
Returns TA to online mode from the online command mode. When TA makes a
data connection, it enters online data mode. The TA typically remains in this
mode until it receives an escape sequence or until the call ends. When it
detects an escape sequence, the TA enters online command mode, where it can
accept AT commands while retaining the online connection. To return the TA
to online mode from the online command mode, enter the command ATO and
press ENTER.
@CONFIG Start ConfigMenu
Values: none
Default: none
Starts TA’s internal configuration utility, which allows you to customize the
configuration for your application. Enter the command while in terminal
mode.
Terminal Adapter S-Registers
S-registers are sections of memory in which values are stored that affect
how the TA operates. S-registers are so-called because each has a name that
begins with the character S. Use the S command to assign a value to or to
read the current value of an S-register. To assign a value to an S-register,
use the command Sr=n, in which r is the register number, and n is the value
you want to assign to the register, e.g., S7=45. To read an S-register value,
use the command Sr?, in which r is the register number, e.g., ATS7?.
