Black Box MD1640A, MD1641A manual S36 Time Between DTR Inactive and Modem Off-Hook

CHAPTER 6: S-Registers

S36

Time Between DTR Inactive and Modem Off-Hook

Unit:	Seconds
Range:	0-255
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:	Seconds
Range:	0-255
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.

S48

Program V.34bis Connect Speeds

Unit:	N/A
Range:	33, 31, 28, 26, 24, 21,19,16,14,12, 96, or 48
Default:	0
Description:	Defines which speed modem connects within
	the scope of Enhanced V.34 mode (e.g., if S48 is
	set to 26, the maximum connect speed will be
	26.4K). This register compensates for line
	conditions that have trouble supporting higher
	Enhanced V.34 speeds (e.g., 33.6K, 31.2K, 28.8K,
	26.4K, 24K...). The modem default is a value of
	0, which indicates a connection attempt of
	33.6K.
