VC> On the basis of what software or are we all supposed to guess?
All of it including my own. Speaking for mine, it totally ignores pkt headers no matter which type but it can create type 2 and 2+. As far as everything else is concerned it looks to either be broken (sysop is unaware of their noncompliancy) or type 2 pkt headers are unsupported by design. If so then all these by default are noncompliant until such time there is a document to replace current standards, which *ONLY* includes type 2 headers.
Does the software you use support type 2?
Life is good, Maurice
