Trumpcard 14400/28800 Modem
Section Four
S5 — Backspace Character
Range
0-32, ASCII decimal
Default
8 (Backspace)
Sets the character recognized as a backspace. Pertains to asynchronous
operation only. The modem will not recognize the Backspace character if
it is set to a value that is greater than 32 ASCII. This character can be used
to edit a command line. When the echo command is enabled, the modem
echoes back to the local communications software 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 Time for Blind Dialling
Range
2-255 seconds
Default
2
Sets the length of time to pause after the modem goes off-hook and before
the modem dials the first digit of the telephone number. The modem
always pauses a minimum of 2 seconds even if the S6 register is set to a
value less than 2 seconds. The "Wait for Dial Tone" call progress feature
(W in the dial string) will override the value in register S6. If option X2 or
X4 is in effect, this register is ignored.
S7 — Wait For Carrier After Dial
Range
1-255 seconds
Default
50
Defines two delay times:
1. During call establishment, this register establishes the time that the
local modem waits for carrier from the remote modem before hanging
up.
2. Sets the length of time that the modem waits when the "Wait For Dial
Tone" call progress feature (W in the dial string) is in effect.
