- Try new ETHERSLIP, I believe it is available in the CRYNWR packet driver
- collection. It does slip, but packages it into a class one driver
- (like Ethernet).

-
- With ETHERSLIP, it already works. The only thing you ought to do is
- reduce the transmission size by adding the following line to your
- WATTCP.CFG file:
- mss=512
-
- Be certain to download the latest WATTCP code from sunee.uwaterloo.ca
- [129.97.50.50]. The latest version has a fix which pertains to the
- smaller packet sizes of ETHERSLIP.

- The old ETHERSLIP was an excellent effort and first version. Joe Doupnik
- changed its operation so it no longer uses interupts and no longer
- drops data. I think it was added to CRYNWR collection, but is otherwise
- available from netlab.usu.edu with a little searching.
