3270-Type SNA Devices
3270-Type SNA Devices
SNA devices such as 3270-type terminals and printers can be connected with HP
applications through the high-level 3270 interface of the SNAX/XF and SNAX/APN
software products. (The interface is functionally equivalent to AM3270 and TR3271 but
supports devices using bit-synchronous protocol.) For more information about
connecting SNA devices, see Section 7, HP NonStop S-Series Systems Network
Architecture (SNA) Network Connections.
HP 6530-Family Terminals and Terminal Emulators
HP 6530 terminals and terminal emulators interact with a NonStop S-series server in
two different modes:
You can connect HP terminals to your NonStop S-series server using X25AM for X.25
connections, or SNAX/XF for multipoint connections, in addition to LAN connection
methods using the AWAN access server or the AWAN 3886 family of servers.
Finally, HP offers a product called EM3270, which allows an HP terminal or HP
workstation to emulate an IBM 3270 terminal. This product is suitable when you want
the same HP terminal or workstation attached to a NonStop system to use applications
on both the NonStop S-series server and the IBM host.
Conversational mode The terminal interacts with the host character by character.
Block mode The terminal transmits and receives blocks of characters.
Up to 12 individually addressable pages of data can be
stored in memory at one time.
