	The goal of this project is to give a CoCo a simple way to do TCP/UDP/IP based communication across Ethernet. This will allow clients to be written to handle things such as FTP, telnet, smtp/pop mail, HTTP requests, etc. A CoCo, under RS-DOS or OS-9, could establish a connection to a remote server, then read and write data to that server in whatever format the protocol needs.

			== Existing Solutions ==
			* Software [[KA9Q]] under OS-9 was able to dial in to a SLIP ISP connection and do some internet access.
			* [[DriveWire]] has extensive internet support.

	* 2013/03/28 - Work began on a Hayes modem "AT" command parser, which would run on the Arduino and control the Ethernet operations. The rough code for handling the "+++" escape sequence has been posted to [http://appleause.com/2013/03/30/parsing-hayes-modem-at-commands-part-2/ my website]. The next step is to write an "AT" command parser and link it to the Ethernet code.		* 2013/03/28 - Work began on a Hayes modem "AT" command parser, which would run on the Arduino and control the Ethernet operations.

			* 2013/04/08 - There is a Wizpro Serial-to-Ethernet adapter available that uses the same chipset that is found in the Arduino Ethernet shields. It has been seen online for as low as $22, though [https://www.sparkfun.com/products/9476Sparkfun.com has it] for $30 and lower shipping fees. This device, with a cheap power supply, could be plugged up to the CoCo's RS232 port. It may be an easier and cheaper solution -- needing only software. Aaron Wolfe reports that the DriveWire internet suite (telnet, inetd, etc.) could be used directly or with minor modifications with something like this.

This add-on board was going to bring all kinds of hardware expansion to an existing CoCo, effectively eliminating the need for a bunch of external hardware like MultiPaks and hard disk interfaces.

	One of the possible items on the Superboard was going to be an iChip from [http://www.connectone.com ConnectOne]. The iChip was a serial-to-internet converter, and was available in a modem (serial) version or an Ethernet version. It contained all the low-level protocol and application layers, and presented them to the host system as simple Hayes modem style commands. Instead of dialing out to a BBS by issuing the command "ATDT 555-1212", the ConnectOne device allowed for "dialing" out to an IP address, such as a web server, and then reading/writing the data from that server.

+The interface will act as an intelligent converted between Ethernet TCP/UDP/IP data and RS232 serial data. The CoCo will connect to the device via RS232, and the device will handle the TCP/UDP/IP stack and just pass between the CoCo and remote internet connection. Instead of actually supporting all the application layer things (like e-mail SMTP/POP), the device will rely on the CoCo to handle that part.
