The PC/TCP Corporate Notes 4 Version 2 series is a major rewrite of the PC/TCP Version 1 series. The important differences are a few new Hello applications, an entirely new Development Kit, and a news@ftp is the new FTP Terminate-and-Stay-Resident Software newsletter for those (TSR) kernel for PC/TCP Version who need to keep up with what 2. we're doing.

The new programs are tar, which allows you to back up your PC's entire hard disk to a UNIX system over the network, and supdup, another remote login program which Lisp machine users should find particularly useful. New features include 43 line support for EGA displays in telnet and rlogin, and support for wildcards and recursion in rcp. The Version 2 Development Kit is quite different from the Version 1 Programmer's Libraries. For one thing, the programming interface is entirely different - it had to be redesigned for the kernel. The new programming interface is much easier to use, and much easier to call from languages other than Microsoft C.

PC/TCP Compatibility with VINES There are several network and NetWare interfaces for the PS/2 MicroChannel already on the Many proprietary LAN system market. 3Com has introduced users (people running Banyan the 3C523 Ethernet interface, VINES, Novell NetWare, ViaNet, Ungermann-Bass the NICPS/2 Lifenet, Microsoft Networks, or Ethernet interface, and Proteon other systems) want to use the p1800 ProNET-10 token ring TCP/IP to communicate with interface.

Almost always, it is the most recently loaded one that will be able to access the network. PC/TCP and NetWare Fortunately, there is a FTP Software and Proteon have solution to this problem.
