+#How TPG26x comms work:
+#First send a command (e.g. ask for the pressure) then the device will return ACK.
+#Then send ENQ to get the actual values.
+
+#According to the streamdevice manual, once an "out" is sent access to the
+#device is exclusively locked until the WHOLE protocol is finished.
+#This should mean that we do not need to worry about commands interrupting each other
