     8Refer to the [wiki:../UART UART usage] page for an overview of how the 802.11 design uses the UART cores on each CPU.

     10The normal UART output on boot of the AP application is:

     23Press the Esc key in your terminal to access the UART menu

     25
     26The AP boot message includes the initial SSID (WARP-AP) and wireless MAC address for the node ({{{40-D8-55-04-21-4A}}} in this example).
     27
     28Hitting the {{{ESC}}} key will show the AP's interactive menu:
     29{{{
     30********************** AP Menu **********************
     31[1] - Interactive AP Status
     32[2] - Print Queue Status
     33[3] - Print all Observed Statistics
     34
     35[c/C] - change channel (note: changing channel will
     36        purge any associations, forcing stations to
     37        join the network again)
     38[r/R] - change default unicast rate
     39[s]   - change SSID (note: changing SSID will purge)
     40        any associations)
     41*****************************************************
     42}}}
     43
     44Option {{{1}}} will show a sub-menu with commands to reset all Tx/Rx statistics and to de-authenticate all stations.
     45
     46Option {{{2}}} will show the current allocation of Tx queue descriptors among the existing Tx queues. For example, the following shows 15 packets are queued for transmission (one multicast, 5 for AID 1, 9 for AID 2):
     47{{{
     48Queue Status:
     49 FREE || MCAST|     1|     2|

     54
     55During normal operation the AP will print UART messages as stations join and leave the AP's network. For example, when the first client joins the AP:
     56{{{
     57Authenticated, Unassociated Stations:
     58
     59(MAC time = 404586220 usec)
     60|-ID-|----- MAC ADDR ----|
     61| 01 | F0:D1:A9:6C:86:A6 |
     62|------------------------|
     63
     64Authenticated, Associated Stations:
     65
     66(MAC time = 404609451 usec)
     67|-ID-|----- MAC ADDR ----|
     68| 01 | F0:D1:A9:6C:86:A6 |
     69|------------------------|
     70}}}
     71
     72The first message shows the client part way through the association handshake (post authentication, pre association). The second message shows the client successfully authenticated. As more clients join and leave the BSS these node lists will grow and shrink.
