Multi-Tech Systems BA-Series manual Reading and Assigning S-Register Values

Chapter 5 - S-Registers

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.

S48

Program V.34bis Connect Speeds (2834 Series only)

Unit:	N/A
Range:	33, 31, 28, 26, 24, 21,19,16,14,12, 96 and 48
Default:	0
Description:	Defines which speed modem connects within the scope of Enhanced V.34 mode
	(e.g., S48 = 26 means maximum connect speed is 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.

5.2Reading and Assigning S-Register Values

The S command is used to assign a value to, and to read the current value of, an S-Register. To read an S-Register value, enter the letter S followed by the S-register number and a question mark (?), then hit RETURN. For example, entering ATS7? and hitting RETURN displays the value of S- Register S7 in a 3-digit decimal form. The number 8 would appear as 008, the number 30 would appear as 030, and the number 255 would appear as 255.

To assign a value to an S-Register, enter the letter S followed by the S-Register number and an equals sign (=), and then a decimal response to the message “ENTER THE NEW VALUE IN DECIMAL FORMAT”. Convert all ASCII characters to their decimal equivalents before entering them. S-Register decimal values range from 0-127 for ASCII characters, or 0-255 for numeric values.
