After concentrating in recent years on MS-DOS and OS/2 communications software, Rabbit Software Corp of Malvern in Pennsylvania has gone back to its Unix roots with a new set of products to provide IBM 3270 emulation over SNA for Unix, Xenix and AIX operating systems. RabbitPlus 3270 enables users to execute local applications while connected with the host, download information from the host for local processing, transfer files between host and 80386-based personal computers, and to have multiple host sessions active simultaneously. Another product, Netcom II, provides X25 for Unix and Xenix 386 systems to connect up to packet-switched wide area networks. And RabbitPlus RJE emulation deals with IBM remote job entry devices such as card readers, punches, exchange devices, printers and consoles. Future plans include LU 6.2/PU 2.1 communications.
