TEDIT and TACL Interface Commands
TEDIT and TACL Interface
E–4 058059 Tandem Computers Incorporated
Protocol When TEDIT sends a message to the TACL code requesting a response, a
simple protocol is used. The TACL code decodes the protocol for
information that describes the current state of the TEDIT process.
Once a TEDIT process is started, TEDIT sends (in the protocol) these four
lines of information:
1 dvol sheight swidth stwidth
2 fn mode line# col row wsiz regline# regcol
3 text of cursor line
4 text of command line
Line number of the protocol
Information in the line
of the protocol
When TEDIT sends a message, all fields on a line are separated by a single
space and are included in the message. Table E-1 describes each field of
each line.
Note There are two additional lines in this protocol, but they only appear under certain conditions;
they are line 5 and line 0. Line 5 is sent after you give a response to a prompt (it is discussed
later in this appendix under PROMPT). Line 0 is sent only with the TACL command (this is
discussed later in this appendix under TACL).
