Get pressure setpoint via RS232 command

[mtrellet]

I am controlling the PX-345 through the RS-232 port. I can set and query successfully. I do not see a command to Read the current pressure setpoint. Alpha can be set and checked, pressure SP cannot (that I can see).

The query equivalent of: CHAN:1P:XXX

I tried the question mark, no success.
