- include/misctxrx.h (wait_for_interrupt), lib/misctxrx.c (wait_for_interrupt): replaced sleep_us*timeout limiting mechanism with a single timeout value in milliseconds - lib/misctxrx.c (wait_for_interrupt): use atrf_interrupt_wait instead of polling - lib/misctxrx.c (wait_for_interrupt): cleaned up control flow - lib/misctxrx.c (run, die, wait_for_interrupt): renamed variable "run" to more specific "sigint" - atrf-txrx/atrf-txrx.c (ping_rx, ping): pass timeout in milliseconds, not deciseconds - atrf-rssi/atrf-rssi.c (sweep), atrf-rssi/gui.c (sweep), atrf-txrx/atrf-txrx.c (init_txrx, receive_message, receive_pcap, receive, transmit, transmit_pattern, ping_tx, ping_rx), atrf-xmit/atrf-xmit.c (init_tx, init_rx, xfer_one), lib/cwtest.c (enter_test_mode_230, start_test_mode_231): updated use of wait_for_interrupt
