S11

Tone Dialing: Tone Spacing and Duration

Unit:	Milliseconds (mSec)
Range:	1-255
Default:	70
Description:	S11 sets the speed of tone dialing (spacing and
	tone duration times). The default value is
	70 mSec, meaning that each tone is on for
	70 mSec with a 70 mSec pause between each.
	The minimum S11 value allowed by most
	telephone systems is 50 mSec. Very few
	telephone systems can handle anything faster
	than that. The maximum S11 value is 255 mSec.

S13

Remote Configuration Escape Character

Unit:	Decimal equivalents of ASCII characters
Range:	0-127
Default:	37 (%)
Description:	S13 defines the remote configuration escape
	character (which becomes your modem’s
	remote configuration character). The default is
	three percent symbols (%%%). When the S13
	character is entered three consecutive times
	from a remotely connected site, your modem
	responds with its Remote Configuration
	procedure.

Range:	10-255
