S24

PBX/CBX Disconnect Drop Time for DSR/CTS/CD

Unit:	50 mSec.
Range:	0-255
Default:	20
Description:	Some PBX and CBX phone systems require the modem’s DSR, CTS, and/or CD
	signal(s) to behave in a certain manner when calls are disconnected. The modem’s
	&R, &S, and &C commands cause the modem to drop these signal(s) for a specified
	time period upon disconnect, and then bring the signal(s) up again. S24 defines the
	length of time that the signals drop. The default setting of 20 results in a one second
	drop time, which is what most PBX/CBX systems with this requirement need.

S25

DTR Dropout Time

Unit:	100 mSec.
Range:	0, 1 through 255
Default:	0
Description:	S25 defines the amount of time that DTR must be dropped before the modem
	disconnects. Typically, a disconnect occurs when DTR is dropped for 50
	milliseconds or more. This dropout time can be increased, up to a maximum of 25.5
	seconds. The S25 unit value for zero is the default value of 50 mSec. For values
	from 1 through 255, the unit value is 100 mSec.

S26

Failed Password Attempts

Unit:	1 failed attempt
Range:	0-255
Default:	0
Description:	S26 counts the number of times there has been a failed password attempt. For
	example, if you entered ATS26? the message 003 would be displayed, meaning
	someone has failed three times to gain access to your modem using its password
	security system.

S29

Local Inactivity Timer

Unit:	minutes
Range:	1-255
Default:	20
Description:	S29 defines the amount of idle time that can elapse between AT commands after the
	SETUP password has been entered. If this timer expires, the LOGIN and SETUP
	passwords will have to be re-entered. S29 only takes effect when the modem has
	been sent a #DB1 command, which secures the modem from local and remote
	configuration or dialing (i.e., no AT commands can be sent until the LOGIN and
	SETUP passwords have been entered).
