Individual Bit Command S n . # = v
Some operators use AT commands as the primary method of changing
S-register options. However, some options stored in registers do not
have an associated AT command. For these options, the individual bit
AT command can be used to change the setting of the bit controlling the
option.
To change a single bit value within a register
Enter ATSn . # = v
where n = register number # = bit position 0 through 7 v = bit value 1 or
0
Example:
S-register 27, bit 2 selects between dial-up or leased line
operation.
AT command method:
AT&L selects dial-up operation (sets S27 bit 2 to 0)
