S5 Command line editing character (user defined)
This register sets the character recognized as a backspace and
pertains to asynchronous transmission only. The modem will
not recognize the backspace character if it is set to an ASCII
value greater than 32. This character can be used to edit a
command line. When the echo command is enabled, the
modem echoes back to the local DTE the backspace
character, an ASCII space character, and a second backspace
character. This means a total of three characters are
transmitted each time the modem processes the backspace
character.
S6 Wait before dialing
This register sets the length of time, in seconds, that the
modem must wait (pause) after going off-hook before dialing
the first digit of the telephone number. The modem always
pauses for a minimum of two seconds, even if the value of S6
is less than two seconds. The wait for dial tone call progress
feature (W dial modifier in the dial string) will override the
value in register S6.
