Multi-Tech Systems MT2834BA Series S30 Inactivity Timer, S32 Time Elapse for Escape Sequence

Chapter 6 - S-Registers

S30

Inactivity Timer

Unit:	1 min.
Range:	0-255
Default:	0
Description:	S30 causes the modem to disconnect if no data is transmitted or received for a
	specified time. This timer runs during both Reliable and Normal error correction
	connections. The timer restarts any time a data character is passed through the
	serial port (either sent or received). If noise on the phone line causes an error to be
	received during Normal mode, this also restarts the timer. The default value is off (0).
	The inactivity timer is disabled by setting S30 to 0, which is the factory default
	setting.

S32

Time Elapse for Escape Sequence

Unit:	1 second
Range:	0-255
Default:	20
Description:	S32 sets the time period to validate the escape sequence. If the time interval expires
	before the escape sequence is employed (by hitting RETURN), the escape
	sequence is aborted. The default is 20 units.

S34

Buffer Length of Command Mode...After On-line Escape Sequence

Unit:	ASCII Character
Range:	0-60
Default:	10
Description:	If the number of characters after AT exceeds the S34 buffer length value, the buffer
	is cleared and the escape sequence is aborted.

S36

Time Between DTR Inactive and Modem Off-Hook

Unit:	1 Second
Range:	0-255 seconds
Default:	0
Description:	The DTR Busy-out feature uses S-Register S36 to set the time between DTR
	inactive (low) and the modem going off-hook. S36 can be set in one-second intervals
	from 0 to 255 seconds. With the default setting of S36=0, DTR Busy-Out is disabled
	(i.e., DTR won't Busy-Out).

S37

Time Between DTR Active and Modem On-Hook

Unit:	1 Second
Range:	0-255 seconds
Default:	5
Description:	S37 sets the time between DTR being active and the modem going on-hook(not
	busy). S37 will only function in conjunction with S36.
