IBM BSC 3270 Devices

You can use the AM3270 input/output process (IOP) to connect IBM 3270 devices to

your NonStop S-series server. The devices must be connected to a point-to-point or

multipoint line controlled by the BSC protocol. AM3270 allows application programs on

a NonStop S-series server to communicate with terminals and printers on the line by

using file-system procedure calls. When used in conjunction with the TR3271 IOP, it

supports a passthrough configuration in which data is transferred transparently

between an IBM host and 3270 terminals attached to the NonStop S-series server.

(TR3271 controls the line to the host, and AM3270 controls the line to the terminals.)

HP page-mode products such as Pathway/TS and PS Text Edit (TEDIT) support 3270

terminal formatting, making it easy to use those devices with NonStop S-series

servers. An AM3270 IOP can support up to 64 devices.
