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,socks):
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_EVEN
conn1.timeout=1
except Exception,e:
print 'port is Buzy'
sys.exit(-1)
print '------------------------------'
print 'getSupportedBaudrates',conn1.getSupportedBaudrates()
print 'getSupportedByteSizes',conn1.getSupportedByteSizes()
print 'getSupportedParities',conn1.getSupportedParities()
print 'getSupportedStopbits',conn1.getSupportedStopbits()
print '------------------------------'
print 'getBaudrates',conn1.getBaudrate()
print 'getByteSizes',conn1.getByteSize()
print 'getParities',conn1.getParity()
print 'getStopbits',conn1.getStopbits()
print '------------------------------'
print 'port is in use',conn1.portstr
list1 = []

command = ['AT','ATI','ATl1','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.getName(), 'counter :',th1.count
th1.join()

print time.ctime()

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

command = ['AT','ATI','ATl1','AT+GMMM']

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

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.

It's quite likely that you do NOT want to regard this as
a "serial port" device as commonly understood. It's even
more likely that you're going to be very happy once you
start reading about gammu <URL: http://www.gammu.org/ >,
an open-source project (or collection of open-source pro-
jects) focussed on mobile telephony handset devices,
especially those from Nokia.

Gammu works particularly well with the 6610 and closely-
related handsets, in my experience; I've been using it so
for a couple of years.

What's your preferred (desktop) operating system? Which
cable did you buy? Is it compatible with one made at the
Nokia factories? Not all USB cables are alike ...
