You're strcmp() logic is backwards, tho.  You're thinking about it too hard,

I just went to IETF.ORG and looked for a more recent TN5250E draft.  There
are two other successful codes:

I901 - Virtual device has less function than source device.
I906 - Automatic logon requested but not allowed, sign-on will follow.

There is one code which starts with an I that is an error code, I904.  All
other failure codes do not start with an I.  The text for I904 is:

I904 - Source system at incompatible release.

This was in addition to two other issues, the first was that we were looking
at the wrong part of the packet for the response code (it changed in 0.15.1,
and this part of the code was not adjusted), and we weren't translating the
response code from EBCDIC to ASCII (??? Could this have ever worked? ???).

Those issues have been fixed, and we now accept all three success codes to 
start up.  The I904 code scares me, however, because it looks like it used
to be a success code at one point.  If someone has an issue with the new
version (0.15.7) which I will be releasing in a few minutes, please let me
know.

I also added a lookup table of response codes -> error text.  If someone
would care to internationalize tn5250 and provide translations for the
error messages, that would be appreciated.  (No, I'm not specifically talking
to you, Gomez, but it would be nice... :)  It's one of those things which
I'll get to sooner or later which means never ...

FYI: The newest TN5250E Internet Draft is at:
