if it differs by more than 0.01 dBm from the level specified - tools/atspi-txrx/Makefile (LDLIBS): added -lm, for fabs() - tools/atspi-txrx/atspi-txrx.c (transmit, usage, main): add optional command-line argument with the number of times to send the message - tools/atspi-txrx/atspi-txrx.c (receive, transmit, die, main): return and clean up on ^C - tools/tools/lib/misctxrx.c (wait_for_interrupt) return and raise SIGINT for the caller's signal handler on ^C
