Hewlett-Packard's IMF Products

Hewlett-Packard offers three different IMF products: SNA IMF/V on MPE V, SNA IMF/XL on MPE XL, and IMF/3000 on MPE V. SNA IMF/V and SNA IMF/XL use Synchronous Data Link Control (SDLC) protocol. IMF/3000, which runs only on MPE V, supports either Binary Synchronous Communications (BSC) or SDLC protocol. An HP 3000 running IMF/3000 functions as a Type 1 node.

You can migrate from IMF/3000 to SNA IMF/V (on MPE V) with minor modifications to your HP application programs. Appendix F “Differences Between IMF/3000 and SNA IMF/V” of this manual describes the differences between IMF/3000 and SNA IMF/V.

	NOTE: IMF/3000 is currently supported only on MPE V.

This manual describes Pass Thru mode for both SNA IMF/V and SNA IMF/XL. Programmatic access mode for SNA IMF/V and SNA IMF/XL is documented in the SNA IMF Programmer's Reference Manual. The IMF/3000 product is documented in the IMF/3000 User/Programmer Reference Manual.

	NOTE: In this manual, the term SNA IMF is used when the information being given is true for both SNA IMF/V and SNA IMF/XL. The terms SNA IMF/V and SNA IMF/XL are used when a distinction between the two products is necessary. The term IMF/3000 refers to the IMF product on MPE V that supports BSC protocol.
