Status Registers

Note

Not all registers can be set by the ATSn=v (or ^v) command. Some registers are for reference only.

To change the escape character from + to the Esc key (ASCII value of 27) enter

ATS2=27

To return the modem to the command mode press the Esc key three times:

(pause) Esc Esc Esc (pause)

Individual Bit Command — Sn . # =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, and v = bit value 1 or 0.

For 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). AT&L1 selects leased line operation (sets S27 bit 2 to 1).

Individual bit method:

ATS27.2=0 selects dial-up operation (sets S27 bit 2 to 0) ATS27.2=1 selects leased line operation (sets S27 bit 2 to 1)

Note

This way of selecting options can be used on all S-registers except read only registers.
