These two "question/explanation" are from two different sources.
After reading the first question/answer I understood that an off-board severs mediates between any industry-standard protocol and legacy-proprietary protocol to facilitate communication. However, second question/answer specifically talks only about forwarding SSL request via serial cable to mainframes.
Although the question-statement for these questions differ they still imply different things in their fundamental concepts.
Friends with legacy experience please share your opinion.
Thank you!

1. What is an off-board server?
An off-board server is a server that executes as a proxy for a legacy system. It communicates with the legacy system using the custom protocols supported by the legacy system. It communicates with external applications using industry-standard protocols.

2. What is an off-board server used for?
An off-board server is used enable secure remote access to mainframes. This is done typically done by forwarding SSL requests to the mainframes via serial connections. It is not an application server that can take up complex business logic processing.

I feel that both answers are basically saying the same thing with the exception of that pesky word "secure" on the second description.
First off, I hate describing anything as "secure" since the word has different meanings for different people.
Secondly, I think security has nothing to do with the concept of an off-board server. It surely might be "secure" but that is not a required characteristic.
Lastly, the second description just provides a possible implementation for an off-board server. I don't think the author intended it to mean ALL off-board servers must use SSL and serial communications. SSL is just one example of an industry-standard protocol to talk with off-board servers and serial communications is just one example of a custom protocol for legacy communication. He could have including many other example as well.
