Appendix C
ASCII Commands for the USERPAK Option
C3
Read String Data Command
The Read String Data command can be used to obtain the defined attributes
and string text of the specified string.
The Read String Data command takes this format:
>OR, p, s
Where: p = number of viewport (or letter of serial port)
s = number of string
The response from the CVIM module takes this format:
Ax Cx, text
For content definition of the response fields, refer to the Write String Data
parameter descriptions.
Suspend / Resume Serial Port Output Command
The Suspend / Resume Serial Port Output command can be used to disable or
enable USERPAK serial port output for a specified serial port.
The command takes this format:
>OS, p, st
Where: p = letter of serial port (A or B)
st = status of serial port, where st = 0 or 1:
st=0 disable USERPAK serial port output
st=1 enable USERPAK serial port output
The default setting for each serial port is st=1 (USERPAK output enabled).
When USERPAK output is suspended, no USERPAK serial messages will
be transmitted automatically at the completion of an inspection. The Force
Print command can still be used to cause a message to be transmitted (see
Force Print Command in this appendix).
Write Display Command (Enhancement)
The Write Display command, currently available with the base CVIM
module operating system, is enhanced when the USERPAK option is
installed (refer to the Select Image Displayed command in the CVIM
Communications Manual). The Write Display command is enhanced to
allow the selection of the page number, along with the selection of the
display page.
