Description
Command line contains a syntax
error, or LU97 is unable to
execute a command contained
in a command line. This code is
issued if a command does not
exist or if the parameter
supplied is outside the
permitted range. Under X0, X1,
X2, and X3, this result is used
instead of DELAYED and
BLACKLISTED.
For X1, X2, X3, and X4, line
speed is 1200 bps, and LU97 has
been instructed to report the
line speed upon connecting.
For X2 and X4, LU97 has been
instructed to wait for a dial tone
during dialing, but none is
received.
For X3 and X4, busy tone
detection is enforced, but a busy
signal is detected when
attempting to originate a call.
For X4 and X5, a call fails to
connect, and the number dialed
is considered "delayed" due to
country blacklisting
requirements.
Line speed of 2400 bits/s.

Line speed of 9600 bits/s.
Line speed of 7200 bits/s.
