server side socket program hangs

[anuradha.k.r at sify.com]

hi,
My one problem is solved,python server no more hangs,but my main
purpose still remains unsolved,my client is not able to establish
connection.my client is a C program running on a windows machine.On
running the python program,in the python shell i get this way
>>>
(cursor)

i assumed my server is waiting for a connection,but my client did not
connect,it failed.
     I tried debugging the python program using the step by step debug
control.it moves till def __init__(Self,parent):
and stops(seems to be waiting).It does not move to the next line.
Can you tell me what is happening? and what is the problem with my
server program?Sorry for the trouble,
thanx
AKR.
