Andrew Moore d79c566f9d From: Sergey Ryzhkov, Serge Vakulenko ... E-mail: <sir@kiae.su>, <vak@zebub.msk.su> added new /dev/wt entries for wt.c version 1.3 8) Some controllers support only 1024 block length. Setting WT_BSIZE bit in device minor number turns on this mode. Minor number structure: 0bfffuuu Fields: uuu - Unit number. It's possible to install up to three tape controllers on the same machine, using DRQs 1..3. Hence, unit number can lie in range 0..2. fff - Tape format number: 0 - /dev/rwt0 - default density (auto select) 1 - /dev/rwt0a - QIC 11 (obsolete) 2 - /dev/rwt0b - QIC 24 (60 megabytes) 3 - /dev/rwt0c - QIC 120 (120 megabytes) 4 - /dev/rwt0d - QIC 150 (150 megabytes) 5 - /dev/rwt0e - QIC 300 (300 megabytes?) 6 - /dev/rwt0f - QIC 600 (600 megabytes?) b - Long block size flag. With this bit set, the driver will perform all i/o operations with the controller using 1024-byte blocks, instead of 512 ones. Some controllers need it (CMS for example). If you Wangtek controller does not stream well, you can try to use /dev/rWt0 device instead of /dev/rwt0 (uncomment needed lines in /dev/MAKEDEV to create it). Block interface (writing blocks less than 2048 bytes) is not functioning pwoperly. Use raw interface instead.
