[GreenKeys] Speed Converters

[gil smith]

Hi Bill:

How about having HeavyMetal talk to TTY-Connect over the net?  I have been 
working with ethernet control using Lantronix XPorts.  One $50 can not much 
bigger than an ethernet 8p8c/magnetics jack provides 
ethernet-to-serial.  HeavyMetal would simply open a tcp socket connection 
to the ip addr of the tty-connect (on a specific port).  Then it just uses 
the same command/message protocol as the serial port version.  You can set 
tty-connect to a fixed ip address, or allow dhcp and discover it when you 
start.

This would allow all of the cool internet features of HeavyMetal (polling 
of news, weather, email...) to be piped to up to three local loops of tty 
machines, with speed conversion on each loop being done by tty-connect.
