There is a space following the period on each line
except for the line containing the END string. This
allows the user to detect when the last line of a
multiple line reply has occurred by looking at the fifth
character of each line to see if it is a space or an
ASCII "E". This convention is true for all commands
returning multiple line outputs.
Output data for the specified modules and ports are in the same
order as requested in the command. Each port's data is preceded
with the port number and a colon. The type and format of the data
returned will depend on how the port is defined and the last
operation performed on the port. This is determined as follows:
If the port is defined as a synchronous mode read port, the
command will return the data from the most recent
synchronous test, using the same data width and format that
was specified when the test was defined. If the port has
been defined as synchronous but no test has been run since
the port was defined, no values are returned (e.g., "001.
07:").
If the port is defined as a synchronous mode write port, the
command will return the most recent write data loaded for
this port, using the same data width and format used to load
the data. If no data is loaded, no values are returned (e.g.,
"001. 07:").
If the port is defined as an asynchronous port, the command
will return the results of the most recent READ or WRITE
command, using the same data width and format used in
that command. If no READ or WRITE commands have
been sent, no values are returned (e.g., "001. 07:").
Example:
Assume that port 0 is a synchronous mode byte-wide (8
bit) port that read in the hex values 9f, 7f, 3f and 1f during
vectors 1-4 of the last synchronous test. Port 1 is a
synchronous mode byte-wide port that wrote out the
decimal values 21, 31, 41 and 51 during vectors 1-4 during
the last synchronous test. Port 2, along with port 3, is an
asynchronous word-wide (16-bit) port that was last used to
read a hex 7AA6. Port 4 is an asynchronous byte-wide
