4.7.15 X (Execute)
Purpose
Format
Description
Directs the Model 263 to execute device-dependent commands received since
previous “x”.
X
The execute command is implemented by sending an ASCII “X” over the bus. Its
purpose is to direct the Model 263 to execute other device-dependent commands
such as F (function) or R (range). Usually, the execute character is the last byte in
the command string (a number of commands may be grouped together into one
string); however, there may be certain circumstances where it is desirable to send
a command string at one time and then send the execute character later.
Programming
1. Command strings sent without the execute character will be stored within an
Notes
internal command buffer for later execution. When the X character is finally
transmitted, the stored commands will be executed, assuming that all commands
in the previous string were valid.
2.
Commands are not necessarily executed in the order sent. In order to force a par-
ticular command sequence, the X character should be included after each com-
mand in the command string (see third programming example).
