Free/non-free? (Only an academic interest, I did not use this driver yet.) Cronyx Tau-ISA driver
URL: http://www.cronyx.ru/hardware/wan.html Announced on a FreeBSD list: ctau(4) driver for Cronyx Tau-ISA was added. Cronyx Tau-ISA is family of synchronous WAN adapters with various set of interfaces such as V.35, RS-232, RS-530(449), E1 (both framed and unframed). This is a second family of Cronyx adapters that is supported by FreeBSD now. The first one was Cronyx Sigma-ISA, cx(4). Cronyx Tau-PCI family will become a third one. The peculiarity of this driver that it contains private code. This code is distributed as obfuscated source code with usual open source license agreement.Since code is protected by obfuscation it is satisfy needs of commerce. On the other hand it still stays a source code and thus it becomes closer to open source projects. I hope this form of private code distribution will become a real alternative to object form.
