*Y[sequence]
Special Access Mode—This command enables special modes and data memory access.
[sequence]
Description
254:Waaaa,dddd
Write hexadecimal data value dddd to hexadecimal data address
aaaa. Only one 254:W command per line.
254:Qaaaa
Read hexadecimal address aaaa. Returns hexadecimal data value
dddd. Only one 254:Q command per line.
2
Enable continuous answer tone for the ATA command. Use ATZ to
clear this mode. For example, the single-line, multiple command is
AT*Y2A.
1
Enable continuous DTMF tone for first digit used in the ATD com-
mand. Use ATZ to clear this mode. For example, the single-line, mul-
tiple command for a continuous DTMF “1” digit would be AT*Y1D1.
0
Exit from 254:W or 254:Q access mode. Must reside on a separate
line and must be the final sequence be sent after the final 254:W or
254:Q command.
+DR=X
Data compression reporting.

Enabled
If enabled, the intermediate result code is transmitted at the point after error control negotia-
tion. The format of this result code is as follows:
Result code
Mode
+DR:NONE
Data compression is not in use
+DR:V42B
Rec. V.42bis is in use in both directions
+DR:V42B RD
Rec. V.42bis is in use in receive direction only
+DR:V42B TD
Rec. V.42bis is in use in transmit directions only
+DS Options
+DS = A
+DS = A,B
+DS = A,B,C
+DS = A,B,C,D
Controls V.42bis data compression function.
A
Direction
0 No compression
1 Transmit only
2 Receive only
3
