Welcome to Hydra !

Today, lots of devices such as robots, cameras, and many other appliances
are connected to the Internet. Most of these devices use very simple
communication protocols like RS-232C. To connect these devices, we need a
sort of gateway between these simple protocol and the Internet. Of course, we
can use a PC as a gateway, but usually PC is too big and expensive to be used
for this purpose. So, we need a very small, inexpensive, general purpose web
server that can be working as a gateway between these simple protocol and
the Internet. The answer is Hydra.
Development
The Hydra was designed and developed by Roy Want, Kurt Partridge, and Frank
Vest at Xerox PARC. Linux porting was done by Jong Hee Kang at the University
of Washington. Hydra is no longer an active project.
