Create a virtual comm port for my device

[techdealer]

I want create a virtual comm port for my device in python.

currently i have this code:

Code: Select all

import win32file
import win32con
import binascii

print "starting"

name = "\\\\?\\USB#VID_07CF&PID_6101#5&15a1c23b&0&1#{a5dcbf10-6530-11d2-901f-00c04fb951ed}"

handle = win32file.CreateFile(
    name,
    win32con.GENERIC_READ|win32con.GENERIC_WRITE,
    win32con.FILE_SHARE_READ | win32con.FILE_SHARE_WRITE,
    None, # no security
    win32con.OPEN_EXISTING,
    0,
    0
)

buffer = win32file.AllocateReadBuffer(2)

err, data = win32file.ReadFile(handle, buffer)
if err == 0:
    print binascii.hexlify(data)
else:
    eg.PrintError("Error")
   
win32file.CloseHandle(handle)

print "finished"

what changes i need do to choose the number of the port that this script should create?
