Description: ESCAPE SEQUENCE GUARD SELECTION
The Escape sequence guard time selection register, S-Register 12, is not
actively used and will report a “0” when queried. Normally the guard time
is used to discriminate between valid and invalid occurrences of the
escape sequence. The duration between escape codes must also be
within the guard time. After the modem recognizes a valid escape
sequence, an "OK" result code is returned. If an escape sequence is
valid, the modem will exit data mode and enter command mode. The ATO
command is used to go back to on-line data state.
Syntax: ATS12=<n><cr>
Parameters: <n> Regardless of the value entered, 0 will always be used.
Response: OK
Example: ATS12=10<cr>
