Disable Modem Result Codes. (See S62 also.)
0 = Enables the following modem result codes:
1 = Disables the following modem result codes:
Intrusion—”i” and “ I ”
Line present—”l” and “L”
Flash—”f”
Ring—”R”
Register S62 can be used to individually re-enable particular result codes.
User Defined Frequency.
0 = Disable.
1 = Enable user defined frequency detectors in A0 and !0 modes.
TIES Escape Operation.
0 = Disable TIES escape operation.
1 = Enable TIES.
AutoOverCurrent Detection.
0 = Disables AutoOverCurrent detection.
1 = Enables AutoOverCurrent detection.
Overcurrent Detected (Sticky).
No Phone Line.
This bit is sticky while off-hook if S82[3] (LCLD) = 1
hook. NLD remains sticky for 800 ms after going from off-hook to on-hook.
Intrusion Detected.
This bit is normally NOT sticky so that the user may monitor/poll for intrusion manually.
However, during dialing and during data mode, it is impossible to monitor/poll this bit.
Therefore, if the Si2400 is either dialing or in data mode, this bit is sticky. If triggered dur-
ing data mode, this bit will remain sticky for 800 ms after the Si2400 goes back on-hook.
Ring Detected (Sticky).
This bit is normally sticky, but is cleared when the Si2400 goes from on-hook to off-hook.
