Enhanced channel adapter

A method for transferring messages between a first and at least one second processor comprising:

• using a first data transfer protocol, transferring messages between the first processor and non-volatile memory;
• storing the messages in non-volatile memory;
• and
• using a second data transfer protocol, transferring messages between the non-volatile memory and a second processor, the non-volatile memory (a) being resettably and logically decoupled from said first and second processors and (b) ensuring message recoverability in the event of a loss of communication between the second processor and the non-volatile memory.

An adapter for transferring messages between a mainframe computer and a second processor, comprising:

• a first processor using a first message transfer protocol;
• non-volatile memory in communication with the mainframe and second processor, resettably and logically decoupled from the mainframe and second processor, storing messages being transferred between the mainframe and second processor to ensure message recoverability in the event of a loss of communication between the second processor and adapter;
• and
• a connector using a second message transfer protocol.
