Description Gerhard Sittig 2020-04-11 20:55:06 CEST 
How to reproduce:

  $ sigrok-cli -d maynuo-m97:conn=bt/rfcomm/98-D3-12-34-56-78 --continuous
  (have data acquired, press a key, acquisition ends)

The device remains in remote control mode. Must get "unlocked" on the 
front panel by means of Shift then Local keys.

This was observed with a M9712 device, firmware V3.2 (according to the 
display upon startup, and Modbus query). The device responds with an 
unexpected model ID 1 (not 54 as the driver source suggests), but otherwise 
is usable and provides measurement data. The serial cable is an HC-05 module 
(RFCOMM), don't have an isolated wired one (vendor's M133 cable).

The driver source suggests that not sending a "goto local" command is by 
design.
