The third mode is the length-limited transparent transmission mode. In this mode, a
user runs the command to send the data length to the MT. After the MT returns
OK
,
the user enters the data to be sent until it reaches the length limit. For example, if a
user wants to send four bytes of data, 0x00, 0x08, 0x1B, and 0x2C, the user runs the
command ^IPSENDEX=1,2,4. After OK is returned, the user enters 0x00, 0x08, 0x1B,
and 0x2C.
Note:
If the length of the entered data is shorter than the requested length, the MT will wait until the
remaining data is entered. If the length of the entered data is longer than the requested length, it
will return CME ERROR.
During the execution command running, the command can be interrupted.
