Adding TCP/IP Ethernet to PIC - how?

[dhouston]

I am looking to save a few lines of data logging text from a PIC to a text file on a PC network.

Are any of the previously mentioned devices capable of this or is a
Delphi/VB program required to receive the data and then save the text lines?

I am not aware of any that can do what you want. You might, however, find a terminal program that can automatically log what it receives. Since I write my own interfaces (using Purebasic) I've never had occasion to search for anything like this. If you pick a module that has a virtual serial port on the PC side (e.g. XPort, NET232) you might be able to use something like http://www.eltima.com/products/rs232-data-logger/ to log the activity.

IIRC, Hyperterminal allows you to manually save what it has received to a text file.
