Go to the URL http://www.crynwr.com for the “Clarkson” (now Crynwr) packet driver collection. The site is a little confusing; click the larger-size “Crynwr Software” link to navigate to packet-related information. Contact is Russ Nelson at Crynwr Software. February 1, 1999 – Russ says that the current DOS packet driver specification that’s in wide use is 1.09. The only significant thing in 1.11 is PPP, and only FTP ever implemented it. DOS is alive and well in the embedded systems market. January 31, 1999, Pavel Aronsky reports that the latest known packet driver specification is v 1.11, by former FTP Software, 1994. It can be found at http://www.devinfo.com/archives/simtel/msdos/pktdrvr/ in the file netzhack.zip. Other information of interest concerning this driver collection may be available from the 3Com FTP site at ftp.3com.com .
