I went ahead and purchased this motorized TV mount from Best Buy.Link
This can either be controlled locally by IR, or serially via RS-232 (see attached RS-232 codes).
2009-01-19_153331_20080703_crestron_protocol_for_Omni_080701 .zip
Presently, I am able to send serial commands. The commands take the form of:
ph_comsendstring(1,"\xAD\xA2\x01\x02\xA5\")<=Left
ph_comsendstring(1,"\xAD\xA2\x01\x05\xA8\") <=Center
While sending one way commands works, ideally I would like to also RECIEVE and intrepret message comming BACK from this unit.
Since I have other RS-232 controlled devices, I tried using the same approach ...see lines 30-90 of the picture below.
Note: This is just an example macro (this is how I control my LG TV).
This approach does NOT seem to work.
Since the rs-232 instructions say all commands are in Hex, I wonder if "ph_comrecvchar(1)" works with Hexadecimal?
Any help with this is appreciated.

The mount is using binary, so you can just switch your ph_comrecvchar(1) to a ph_comrecvstring( 1, 1 ).
From Help...
Quote:
This function is also capable of receiving binary characters as well. Characters with ASCII values from 32 to 125 and not equal 92 will be returned as their standard character counterparts. Characters below 32, greater than 125, or equal to 92 will be returned as an escape sequence consisting of the "\" character followed by three decimal digits representing the ASCII value. For example, the "\" (backslash character) will be returned as "\092". A carriage return character will be returned as "\013". This counts as a single character concerning the number of characters returned. |

...and, of course, get rid of the CHAR( INTEGER()) bit as these will not translate to ASCII. That should be...
Set System [TEMP1] "[TEMP1]" + "[LOCAL1]"
After the string is built, you can compare to your encoded responses, just in decimal not hex ("\xAD" would come in as "\173").

Tony you are AWESOME!!!
As a non-programmer I am not sure I would have ever figured this out.
Thank You!!

Edit
Let me better clarify: With macro logging enabled, it appears that I never see any incoming traffic on my com control, ie, my "COM PORT LG MOUNT" macro is NOT called.
End edit.
++++++++++++++++++++++++++++++++++++++++++++++++++++++
Shoot....it still does not seem to recieve any incoming serial traffic.
This is how I open my serial port:
ph_comopen(1,16,9600,"N", 8, 1, 1, 0, 0, 1, 0, 0, 0, "?","COM PORT LG MOUNT")
I open the above port, send out a
ph_comsendstring(1,"\xAD\xA2\x01\x05\xA8\")
I keep this com control open for about 3 seconds before i close it. That should be plently of time for serial traffic, but the "COM PORT LG MOUNT" macro never gets called.
One way communication is all I can get presently.
