We've bought ours though Yankee Electronics (603) 625-9746, Jo Shatzman is the sales person we normally use. It is a weird package. The assumption is that it is a qnx user wanting access to the unix world, not the other way around. No rlogind, telnetd, inetd, etc. You get rlogin, ftp and the normal tcp/ip libraries. No NFS. The libraries work only with the Computer Innovation's CI86 compiler, not the Quantum compiler. Rlogin is weird, because there is not terminfo (or termcap) for a qnx terminal. I wrote a simple one, but it is not really an good. Because CI86 does not have fork(), whipping up your own inet and any of the other daemons is not a simple job. But it can be done. It only works with the CMC-640 smart ethernet card. This is an expensive card, about $1200, with the qnx software an extra $400, this is quite a package. Of course, depending on usage, you only need one board per qnx network. One board can be shared by all qnx users. We don't do this, so I don't know how well it works. It seems fast enough. Our application is to send large volumes of image data to a number of unix machines and back again. It can keep up, but just barely. All in all, it works. We use it because we have to. We hate it. -Larry
