'?' command not being passed w/ grbl buffering

[stewartoallen]

it seems that all is working correctly except for this. is it possible this is happening in the serial-port-json-server? my tipoff is the "CompleteFake" return below. no other commands do that. i only have one device that requires grbl so i can't test other buffers.

send /dev/ttyACM0 ? {"Cmd":"Queued","QCnt":1,"Ids":[""],"D":["?"],"Port":"/dev/ttyACM0"} {"Cmd":"Write","QCnt":0,"Id":"","P":"/dev/ttyACM0"} {"Cmd":"CompleteFake","Id":"","P":"/dev/ttyACM0"} sendnobuf /dev/ttyACM0 ? {"Cmd":"Queued","QCnt":1,"Ids":[""],"D":["?"],"Port":"/dev/ttyACM0"} {"Cmd":"Write","QCnt":0,"Id":"","P":"/dev/ttyACM0"} {"Cmd":"CompleteFake","Id":"","P":"/dev/ttyACM0"}
