Table E.4: Set Telephone Extension Options
If the line is in use and the modem receives an ATDT command to dial out, the modem will not go off hook and
will display the “LINE-IN-USE” result code. If the modem is off hook and the extension is picked up, the
modem will drop the connection and display the “OFF-HOOK INTRUSION” result code.
AT S registers
The S registers use the following format: ATSr=n<CR> where the “r” is the S register number and “n” is the
parameter to set it to. To read the current contents of an S register, issue an ATSr?<CR> command where “r” is
the register in question. The modem will then display the value of the S register.
