Dial Up Connections on Linux

In this tutorial we will detail how to connect two linux hosts via 56k modems. To do this we will use the following components:

• Two Raspberry Pi's 4 ($35-$55 / each)
• Two Conexant 56k Modems ( https://www.amazon.com/gp/product/B008RZTJC0/ | $17-$20 / each)
• a RJ-11 splitter( https://www.amazon.com/Splitter-Duplex-line-Telephone-Adapter/dp/B07WNDZT6Y | $8-$12)
• A Linksys SPA-2102 ( search ebay for linksys SPA-2102 on ebay | $18-$25 )
• Two RJ-11 cables ( should come with the modems )

'''
This module provides a function ``make_except_hook`` which returns a function
usable as replacement for ``sys.excepthook``.

All imports are done dynamically to make this function a self-contained,
copy/pasteable piece of code.

Requires the "blessings" module to work!
