Well no answers, but I figured out a way to accomplish this. I'll share!
I used a macro program on windows to automate ssh'ing to the 1310, then issued the dot11 linktest command on the device. I then set the logging to debug, and sent the output to my syslog server. Now, every 30 minutes, I get a syslog record of my link state.
This is especially important, these bridges are outside and we are trying to gauge the affect adverse weather conditions will have on them.
