    v34 v35  
    3131   * One of the four timers in the warp_timer core is dedicated to the polling of the UART and User I/O buttons
    3232 * Fixed bug in the function for setting random backoff timers found by forum user domenique (See post [http://warp.rice.edu/forums/viewtopic.php?id=465 here]). Previously the minimum contention window was ![0,7]. This is now ![0,15] like 802.11
    33  * Lowered packet detection threshold from 9000 to 3400. This should improve low SNR detection
     33 * Lowered packet detection threshold from 9000 to 6000. This should improve low SNR detection
    3434 * Raised CSMA threshold from 6000 to 8192. This is more in line with 802.11 and should make nodes more aggressive in the presence of non-decodable interference

    3636'''Using the Design'''
     37 * The <project>/implementation/download.bit is ready to download to WARP SISO or MIMO kits.
     38 * The <project>/system.ace file can be copied directly to a CompactFlash card (without using iMPACT) to program kits via the SystemACE CF interface.
    3739 * The CSMAMAC code uses the UART to control various parameters at run time. Use a terminal emulator set to 57600bps. The following commands are implemented by default:
    3840  * '''P'''/'''p''' : Increase/decrease the packet detection energy threshold by 100
