15.5.2 Description

This command is used to transmit user data through an established connection,
supporting three data transmission modes.
The first mode is the ^IPSEND compatible mode, in which ^IPSENDEX functions as
the old command ^IPSEND.
The second mode is the forced conversion mode. In this mode, a user must convert
the original data from hexadecimal data to character strings before entering them to
the MT. Then the MT converts the data back to hexadecimal data before sending the
data to the receiving end. The receiving end can obtain the original data without
additional processing. For example, if a user wants to send four bytes of data (0x00,
0x08, 0x1B, and 0x2C), the user enters the command ^IPSENDEX=1,1,"00081B2C".
Then the receiving end receives 0x00, 0x08, 0x1B, and 0x2C.

Only the subscriber data in the form of visible characters can be transmitted. To transmit
invisible characters, they must first be converted into visible ones. In addition, subscriber data
cannot contain quotation marks.
