The terminal will normally respond with an '\ character when an
Fo
character is received. Compatibility Mode disables
the terminal's
Ib/'k
handshake. Compatibility Mode causes most control codes to be ignored.
The Read Status, alpha cursor position, and graphic cursor position cause block transfers to the computer system. If the
computer system does not use the
DC1/DC2IDC1
handshake, InhHndShk(G) and InhDC2(H) in the Terminal Configura-
tion menu must be "YES" for these transfers to occur. (Refer to "Terminal Configuration Menu" in Section II).
