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.
