i want to add a timeout to my code

[maehhheeyy]

I want to add a timeout so that when I pull out my gps from my serial
port, it would wait for a bit then loop and then see if it's there. I
also want to add a print statement saying that there is no GPS device
found. However when I run my code and unplug my serial port, my code
will just hang until I plug it back in.
This is my code right now:

def GetGPS():
data = []
#Open com1: 9600,8,N,1
fi = serial.Serial(0, timeout = 1)
print '[gps module] SERIAL PORT OPEN ON COM1:'
can anyone help me please? Thanks.

I tried the code onto my codes but what came out was that in the line
signal.signal(signal.SIGSLRM, handler), an attributeError appeared
reading that 'module' object has no attribute 'SIGALRM'

Are you writing your program on windows, or some other platform which is
not unix?

signal doesn't work on Windows. The timeout parameter to Serial should
suffice...
