serproxy - waiting for clients

I'm running into the same problem, and wonder if it has to do with the cfg file...

when i try telnet 127.0.0.1 5331 it says:

Trying 127.0.0.1...
Connected to localhost.
Escape Character is '^]'.
Connection closed by foreign host.

and in the window running serprozy i get: Failed to open comm port - connection refused

flash connects and says it's trying, but serproxy gives the same warning.

I'm on OS X and don't know how to determine what comm port it's on (in the config i have comm_ports=1), the serial port is /dev/cu.usbserial-A1015S9

heres the whole serproxy.cfg file

newlines_to_nils=true
comm_ports=1 
#don't know how it determines this

comm_baud=19200
#matched in the pde on arduino
comm_databits=8
comm_parity=none

timeout=300

serial_device1=/dev/cu.usbserial-A1015S9
#name from the menu in the IDE

net_port1=5331
#5331 is arbitrary right?
