Welcome to Pure3270’s documentation!

Pure3270 is a self-contained, pure Python 3.10+ implementation of a 3270 terminal emulator, designed to emulate the functionality of the s3270 terminal emulator. It includes a P3270Client class that implements a superset of the p3270 library API natively, providing 100% drop-in compatibility without external dependencies.
