Write hexadecimal data value dddd to
hexadecimal data address
aaaa. Only one 254:W command per line.
Read hexadecimal address aaaa. Returns
Enable continuous answer tone for the
ATA command. Use ATZ to clear this
mode. For example, the single-line, multi-
ple command is AT*Y2A.
Enable continuous DTMF tone for first digit
used in the ATD command. Use ATZ to
clear this mode. For example, the single-
line, multiple command for a continuous
DTMF “1” digit would be AT*Y1D1.
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.
