Thanks Massimo.
If I use cache.ram how can different functions in a controller access
the cached object? Also, is there anyway to specify what happens to
an object with it "expires". In my case it'll be best to close the
connection before it is destroyed.
for example:
def index():
## open COM port on initial page load
ser = cache.ram("ser", serial.Serial(0,9600), 5000) ## can this
timeout be indefinite?
## each ajax request polls until is reads, returns read
## another poll request is immediately kicked off
def poll():
while True:
curCode = ser.read(1)
if curCode:
n = ser.inWaiting()
curCode += ser.read(n)
return curCode
## catch page unload and cleanly close connection to serial port
def close():
ser.close();
