BPR(=)
Purpose
Read or set the back pressure ratio (BPR) mode. This is only available
when using a molbloc-S.
Command:
"BPR =mode"
"BPR=mode, suspend
Query:
"BPR"
Defaults
"BPR=2,0"
Arguments
mode:
suspend:
Remarks
The BPR mode determines the operation when the back pressure ratio
is measured when using molbloc-S to measure flow.
"suspend" argument can be used to leave the BPR valve state in it's
current condition, allowing manual manipulation of the molbox valves
without the BPR function intervening. If the "suspend" argument is not
given, it is presumed to be '0' for normal BPR operation.

baud:
parity:
data:
stop:
Defaults
"COM1=2400,E,7,1"
"COM2=2400,E,7,1"
Remarks
The COM1 port is used to communicate to the molbox RFM.
When the COM1 port configuration of the molbox RFM is
changed, the command reply will be sent at the old COM1
settings,
accomplished at the new COM1 settings.
The COM2 port is used to allow commands to be passed
through the molbox RFM to a device connected to the COM2
port (refer to the '#' command).
