TPS^®/ 3270 BSC Controller is an API which supplies a set of C functions to allow an application to emulate a 3270 Binary Synchronous Communications line terminal or printer session on an IBM^® AIX^® system. The BSC protocol may be either ASCII or EBCDIC. The API contains the basic open, close, read, and write facilities for device emulation. The product also has the ability to function on a multipoint BSC line.

Designed to be used multiple times on a single machine, TPS^®/ 3270 BSC Controller uses a shared library that can be accessed by multiple programs on a single machine. It can be used to handle multiple BSC ports on the same synchronous adapter or on multiple adapters. There is no logical limit placed on the number of ports accessed by the TPS^®/ 3270 BSC Controller product. Also, TPS^®/ 3270 BSC Controller does not take control of the entire adapter if it has more than one port. The other ports may be used for other types of communications such as SDLC or ASYNC lines.

Do you need to write an application to emulate or talk to a 3270 printer or terminal? TPS^®/3270 BSC Controller provides an API to handle basic open, close, read, write functionalities.

PRODUCT POSITIONING

TPS^®/ 3270 BSC Controller is an ideal solution for creating applications to communicate with legacy 3270 BSC host systems.

FEATURES

Protocol Support

TPS^®/3270 BSC Controller currently supports both EBCDIC and ASCII protocol support. Those subsystems can provide:

• · EBCDIC
  - 8-bit data/no parity
  - Transparent 8-bit data
  
• · ASCII
  - 7-bit data/odd parity
  - Transparent 7-bit data
  

The TPS^®/ 3270 BSC Controller line driver, along with TPS^®/ BSC SUPPORT, the device driver and synchronous adapter, can handle inserting and removing BSC control information allowing the application to just handle the 3270 data. Also, the support will handle all necessary standard protocol handshaking. The application only has the responsibility to format its own outgoing 3270 messages and handle the incoming 3270 messages.

Adapter Support

• ARTIC960Hx
• Multiple ports per adapter supported
• Multiple adapters per system supported
• Allows other protocols (i.e., SDLC, ASYNC) to be used on other ports of the same adapter
• Maximums: - Line Speed: 56 Kb
  - Frame Size: 4,090 bytes
