Unexpected Terminal
Behavior with TEDIT
There are known anomalies with some older versions of microcode in
Tandem 6520, 6530, 6530-WP, and 6540 terminals.
6520 Terminal Anomalies The 6520 terminal may exhibit some of the following anomalies with
TEDIT, depending on the version of firmware in the terminal:
Versions C and D: The RECONFIGURE FUNCTION-KEYS always
complain about a field being too long. The terminal is sending back
incorrect data.
Versions C through E: If a modification is performed on the first line
only, then TEDIT does not detect it.
Versions C through G: The 6520 terminal does not always remove
trailing blanks from fields. Although TEDIT compensates for this, a
communication delay results in slow lines.
Version H: TEDIT does not support this version (modified fields fail to
transmit properly).
6530 Terminal Anomalies The 6530 terminal may exhibit some of the following anomalies with
TEDIT, depending on the version of firmware in the terminal.
Version B: After displaying response lines for commands (like
SEARCH, REPLACE, OPENWINDOW, and RENUMBER), the terminal
will occasionally set some incorrect tab stops.
Often, after displaying response lines for commands (like SEARCH,
REPLACE, OPENWINDOW, and RENUMBER), and occasionally, after
a SEARCH command, the terminal screen will show irregular
characters. Use REFRESH to correct the display.
