REGISTERS

Some registers control a single function. Others control several functions
and are bitmapped. We recommend bitmapped registers for reading
modem status only; we suggest you use commands to change the
modem's settings.

Commands to Change or Read Registers

Change the Value of a Register
Sn=x
:Tn=x Changes the value of S or :T register "n" to a new value "x".
Change the Value of the Last Referenced S-Register
=x Changes the value of the last referenced S-register or the
register pointed to with the ATSn command. For example, if the
last register command used was ATS0=2, entering AT=4
changes the value of register S0 from 2 to 4.
Display the Value of the Last Referenced S-Register
? Displays the value of the last S-register referenced in a read,
write, or point to command.
Point to New Register
Sn Where n is an integer from 0 to 27, indicating a register,
instructs the modem to point to the register whose location is n.
This becomes the last referenced register. For example, typing
ATS1 <Enter> places the pointer at register S1 and returns the
command prompt.
Read All Registers
%Rn
%R0 Displays the contents of all S registers in decimal and
hexadecimal integers in tabular format.
%R1 Displays the contents of all :Tn=n commands in decimal and
hexadecimal integers in tabular format.
Read Configuration Register
Sn? Where n is an integer from 0 to 27, indicating an S register.
