The Read Attributes Under Cursor command allows the host to read the character attributes
shown on the screen.
The Read Attributes Under Cursor command is used to:
•
Read the entire screen and send it to a printer.
•
Save a message displayed on the screen, display a new message in the same area, and then
restore the previous message.
•
Test the attribute memory of the TCS remotely.
After receiving this command, the TCS responds by sending the host the attributes of the
character at the current position of the cursor as follows:
Monochrome TCS:
<ESC> [>4 ;<Phi> ;<Pul> ;<Pblink> ;<Prv> ;<Pconcl> n
Color TCS:
<ESC> [>4 ;<Phi> ;<Pul> ;<Pblink> ;<Prv> ;<Pconcl> ;<Pfg> ; <Pbg> ;<Pcc> n
