12.5 Printing/Sending Data
This section describes commands to print and send data.
12.5.1 Sending Data
This section describes commands to send a defined area of data on the screen
through the main communication port (Comm1) using ASCII control functions.
Individual commands address the specific data to be sent.
In send operations, delimiter characters are sent along with data to mark a line
end, transfer complete, or the protect data and its area. Table 12–14 lists the
possible delimiter types. Depending on the scope of data (line, page) and the type
of data (protected, unprotected) that has been sent, different delimiter characters
are enclosed. The individual commands explain which delimiter should be sent
with each command.
Table 12–14 lists the types of delimiters to send data.

All the send data actions in this section, except "Send the Cursor Character"
command, use the following rules:
•
The attributes are not sent along with their data. But a Space character (Hex
20) is inserted between two distinct attribute data to indicate the attribute
difference.
•
During the process of sending characters, the cursor moves to the location of
the character being sent.
•
Protect mode on: The cursor does not move.
•
Protect mode off: The cursor moves to the left margin of the next line.
•
Null characters on the screen are not sent.
•
Delimiter characters:
•
TVI modes and WYSE 325/160/60 PCTerm modes: Defined by
command "Define Delimiters" (Refer to the command for details.)
•
Other personalities: See Table 12–15.
