attempt to write more bytes will be denied and causes the following URC to appear: "

Control how the application provides the data bytes to be sent.

Binary mode
This mode allows sending a number of bytes defined with parameter
1
Interactive text mode
This mode allows the user to type and send 8-bit ASCII characters while the
service is open. Ctrl-Z terminates data input and causes the data to be trans-
ferred.
Interactive text mode requires that the
is set to any value
greater than 0 (though it is not necessary to specify the precise number of
bytes). In this case the
parameter indicates the maxi-
mum length of the data stream without control character CTRL-Z. The
counter is incremented only by the portion of data actually trans-
mitted.
In interactive text mode, the following characters are defined as control codes:
• BACKSPACE ("\x08") deletes the last given character,
• CTRL-Z ("\x1a") terminates the input,
• ESC ("\x1b") aborts the command. An
is ignored in this case.
The V.25 command
also controls the echo mode of the interactive text
mode. If echo is enabled (
1) all characters are echoed until
is reached. Any attempt to input further data ends up with the warn-
ing message 4001 indicated after the data stream has been completed with
CTRL-Z, nevertheless all data within the range of
sent. See also Section
0 disables the
echo mode generally.

Confirmed number of data bytes which can be transmitted via the Internet ser-
vice configured in

) this num-
ber may be less or equal to the value requested with
.
The application has to deliver exactly the number of bytes indicated by
. A 0 value means that no data can be written at this time, i.e.
it serves as a flow control mechanism.
In interactive text mode,
indicates the maximum number
of bytes it can process. Characters above the indicated number are ignored.
