The IBM 3270 Workstation Program allows your IBMPC, XT, AT, PS/2, or 3270 PC emulate 3278/79 display terminals. On a PC equipped with a corresponding emulation adapter and coaxial cable, connection to the host system can be to a 3174/3274/3276 cluster controller, 3745/3725/3720 communications controller, or directly to the 9370 or 4361 (with an Integrated Communications Adapter). The product also supports Token Ring attachment to a 3745/3725/3720 communications controller, 3174 cluster controller in CUT or DFT mode, 3274 cluster controller in DFT mode, or directly to the 9370 Token Ring subsystem controller. The Workstation Program supports up to four SNA sessions, six PCDOS sessions, and two notepad sessions. It also supports LIMEMS version 3.2 to accommodate terminal emulation software and DOS applications beyond the 640K RAM limit. Expanded memory support provides a migration path from the Workstation Program to OS/2 Extended Edition with its Communications Manager (which provides the functionality of the Workstation
Program.) Because it supports LIM/EMS version 3.2, all DOS sessions access the region above 640K. However, only data, not applications, can occupy this region. EMS support is available with IBM's Expanded Memory Adapter (XMA). These adapters can be configured to support EMS or the extended memory used by OS/2. The Workstation Program supports baseband or broadbandPC Network Adapters and full screen 3278 model 3, 4, or 5 support with the 8514/ A display adapter. File transfers are handled via the Send/ Receive protocol and require a host component to be loaded. The Enhanced Connectivity Facilities (ECF) Server-Requester Programmers Interface (SRPI) is supported for the development of programs which take advantage of these protocols. There is additional programming support for 3270 High Level Language Application Program Interface (HLLAPI) and Application Programmers Interface (API). Research IBM 3270 Workstation Program
