connecting to serial port + python

[Japan Shah]

Hello,

I am trying to connect my Nokia 6610 using usb cable,
I have installed usb-serial driver of it.
I hv tested it with Hyperterminal and it works fine.

but when I wrote a python script I am not able to receive the responce
from the device.

import os
import re
import time
import sys
from threading import Thread
import serial

class connect_serial( Thread):
def __init__(self,s ocks):
Thread.__init__ (self)
self.sock = socks
self.count = 0

def run(self):
self.count = 0
try:
while 1:
self.count +=1
if (self.count>=5) :
break

lines = self.sock.read( 100)
if lines:
print lines
print 'read
success-----------------------------------------------'
else:
print 'nothing to read',str(self. getName())
except Exception,e:
print self.getName()

print time.ctime()
print
try:
conn1 = serial.Serial(4 )
conn1.baudrate = '9600'
conn1.parity = serial.PARITY_E VEN
conn1.timeout=1
except Exception,e:
print 'port is Buzy'
sys.exit(-1)
print '------------------------------'
print 'getSupportedBa udrates',conn1. getSupportedBau drates()
print 'getSupportedBy teSizes',conn1. getSupportedByt eSizes()
print 'getSupportedPa rities',conn1.g etSupportedPari ties()
print 'getSupportedSt opbits',conn1.g etSupportedStop bits()
print '------------------------------'
print 'getBaudrates', conn1.getBaudra te()
print 'getByteSizes', conn1.getByteSi ze()
print 'getParities',c onn1.getParity( )
print 'getStopbits',c onn1.getStopbit s()
print '------------------------------'
print 'port is in use',conn1.port str
list1 = []

command = ['AT','ATI','ATl 1','AT+GMMM']

for cmd in command:
conn1.write(str (cmd))
th = connect_serial( conn1)
list1.append(th )
th.start()

for th1 in list1:
print 'started joining',th1.ge tName(), 'counter :',th1.count
th1.join()

print time.ctime()

If the response contains less than 100 bytes, the above line will block.

command = ['AT','ATI','ATl 1','AT+GMMM']

for cmd in command:
conn1.write(str (cmd))

Don't you have to send <ENTERafter each command? "\n"

th = connect_serial( conn1)
list1.append(th )
th.start()

You can't have four threads all reading the same serial port. The device
sends its responses sequentially anyway.
