[Twisted-Python] Com Port

[lucaberto at libero.it]

Hello i have some problem with pyserial.
In one forum peoples said the with twisted serial i can solve this problem.
Can you help me to configure the port as show below:

data baud = 38400
parity= odd
byte delay= 40000
rec timeout = 200
stop bit= 2
serial control line:
dtr = high
rts= low

toggle this line for a reset:

rts. 

and also were i can find some sample of twisted and serial communication

Thanks Luca
