IBM PC Network SNA 3270 Emulation Program is a software package which allows the Personal Computer to emulate a 3274 control unit with an attached 3278/3279 display and a 3287 printer in varying configurations facilitating stand-alone and network operation. This product attaches to a host using SDLC/SNA protocols. The configurability and communications capabilities of a PC Network 3270 makes it usable and adaptable to many situations. All previous IBM PC SDLC products have run at a maximum speed of 9.6K baud. This speed is slow when compared to the speeds at which data is carried across the PC Network 3270 LAN. The gateway PC which will maintain the SDLC link when running in a network environment may have up to 32 other PCs communicating with it simultaneously.
