As the name of h3270 suggests, we consider it related to the x3270 program suite that is maintained by Paul Mattes, which includes x3270, c3270, tcl3270, pr3270, and s3270 (the latter is also used internally as the protocol engine in h3270). Paul Mattes gave us tremendous help during the design of h3270, and he was also quick to add some features to s3270 that we needed.

The development of h3270 is coordinated by akquinet framework solutions GmbH, Berlin, Germany. As of yet, the code was mostly written by André Spiegel, Alphonse Bendt and Carsten Erker, with contributions from Berrin Ileri and Dirk Bogun (akquinet framework solutions).
