This document describes the OpenCBM package, which can be used to control and use serial devices as used by most Commodore (CBM) 8-bit machines. The latest version of the document can be found online at https://opencbm.trikaliotis.net/. OpenCBM consists of a kernel module ("driver") for Linux, FreeBSD and Windows for cables connected via the parallel port, which is almost obsolete on modern PC hardware. Thus, it also includes support for USB based devices, the so-called XU1541 and XUM1541 adapters. Additionally, it has support software and tools to access these old parallel port based cables as well as the more modern USB replacements. On top of that, a few user space support programs to control and use serial devices as used by most Commodore (CBM) 8-bit machines are included. The contains descriptions for the support programs, as well as for the corresponding cables, namely, the XU1541 adapter, the XUM1541 adapter (a.k.a. "ZoomFloppy"), and the XA1541/XM1541 adapter.
