Disconnect Activity Timer—Sets the length of time that
the modem stays online before disconnecting with no
activity on the serial port, parallel port, or telephone
line (Ring, hookswitch flash, or caller ID). This feature
is disabled if set to 0.
Hang Up Delay Time—Maximum delay between
receipt of ATH0 command and hang up. If time out
occurs before all data can be sent, the NO CARRIER
(3) result code is sent (operates in V.42 mode only).
“OK” response is sent if all data is transmitted before
timeout. S38 = 255 disables timeout and modem dis-
connects only if data is successfully sent or carrier is
lost.
Data Pattern - Data pattern generated during &T4 and
&T5 transmit tests.
0 – All spaces (0s)
1 – All marks (1s)
2 – Random data
Blacklisting - The Si2403 will not dial the same number
more than three times in three minutes. An attempt to
dial a fourth time within three minutes will result in a
“BLACKLISTED” result code. If the blacklist memory is
full, any dial to a new number will result in a “BLACK-
LIST FULL” result code. Numbers are added to the
blacklist only if the modem connection fails. The %B
command will list the numbers on the blacklists.
0: disabled
1: enabled
Dial Attempts to Blacklist.
When blacklisting is enabled with S42, this value con-
trols the number of dial attempts that will result in a
number being blacklisted.
Blacklist Timer.
Period during which blacklisting is active
Minimum On-Hook Time—Modem will remain on-hook
for S50 seconds. Any attempt to go off-hook will be
delayed until this timer expires.
Number to start checking for an outside line on a PBX.
