- Not last I checked. Even the cheapest Ethernet cards around here run

- Well, then you've got to write something to run on the connected
- machine to deal with this `simple' communications layer (which may
- not be so simple; networking is not nearly as easy as it looks).
-
- You've basically got two choices here. 1) use a simple but proprietary
- communications layer, thus chucking interoperability out the window
- and putting yourself more or less in the position of those lovely
- modems that get the CPU on a PC to do a lot of the work, or 2) use
- open standards such as TCP/IP, and upgrade the CPU and the memory
- in the modem to support this, not generally an inexpensive proposition.
