Installation

Examples

Getting module version

#!/usr/bin/python
#-*- coding: utf-8

import tn3270

print("Using py3270 Version " + tn3270.version() + " revision " + tn3270.revision())

Getting pw3270 version

#!/usr/bin/python
#-*- coding: utf-8

import tn3270

session = tn3270.Session(":a")

print("Using PW3270 version " + session.version + " revision " + session.revision)

Connecting first pw3270 window to host (if not connected), getting contents

#!/usr/bin/python
#-*- coding: utf-8

import tn3270

session = tn3270.Session(":a")

if session.reconnect.try_activate():
	print("Reconnecting to host")
	session.wait(10)

print(session)

Connecting to host by url, getting some information.

#!/usr/bin/python
#-*- coding: utf-8

import tn3270

# Get TN3270 headless object
session = tn3270.Session("")

# Connect to host with 10 seconds timeout
session.connect("tn3270://localhost:3270",10)

# Show connection state.
print("Cstate: " + str(session.cstate))
print("Width: " + str(session.width))
print("Connected: " + str(session.connected))

# Show cursor position
print(session.cursor)

# Search for string on terminal
print(session.find("Host"))

# Count string
print(session.count("Host"))

# Get 38 characters at position 14,22
print(session.get(14,22,38))

session.disconnect()

input("Press enter to exit")
