I am assuming there is a single ser object for ALL users.
indefinite=10*10
ser = cache.ram("ser+, serial.Serial(0,9600), indefinite)
def index():
## open COM port on initial page load
return dict()
## 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();
cache.ram('ser',None,0) # delete it from cache (0 is now!)
