  1. The following is the debug output resulting from starting sigrok-cli like this:
  2. $ ./sigrok-cli -d agilent-dmm:conn=/dev/tty.AgilentU1177A-2C30E6-SPP --samples 1 -O csv -l 4
  3.  
  4. The code in libsigrok/hardware/agilent-dmm/api.c has been changed a bit so that a message is
  5. logged for every serial_* call, giving the return value and errno.
  6.  
  7. sleep(2) has been inserted before various calls, resulting in the output below.
