It provides a simple API: you supply callback functions to read from and write to your communication channel, then call send() or recv() to transfer a file. The protocol handles framing, checksums or CRC validation, retries, and flow control\u2014all the low-level details of reliable block-based transfer.\n\nThe package has no external runtime dependencies and supports Python 3.6 and later. It is commonly used in embedded systems development, firmware updates, and legacy equipment integration where XMODEM remains the standard or only available transfer method. Recent versions have addressed timing issues and improved retry semantics.","worth_installing":"Yes. xmodem is a stable, actively maintained, dependency-free implementation of a protocol you need if working with serial devices or legacy systems. MIT license, low install friction, and no known vulnerabilities make it a straightforward choice for projects requiring XMODEM support."},"id":"xmodem","links":{"html":"https://skillfed.io/packages/xmodem","md":"https://skillfed.io/packages/xmodem.md","pypi":"https://pypi.org/project/xmodem/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-03-04","license_spdx":"MIT","license_treatment":"permissive","name":"xmodem","python_support":"supports_current","summary":"XMODEM protocol implementation."},"popularity":{"monthly_downloads":536368,"position":6126,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.5.0"}
