- * the fourth letter is one of pqrstuvwxyzabcde indicating
- the 1st through 16th series of 16 pseudo-ttys each, and
- * the fifth letter is one of 0123456789abcdef indicating
- the position within the series.
-
- These are the old-style (BSD) PTY devices; Unix98

- master multiplex (/dev/ptmx) to acquire a PTY on
- demand.

+ The OnStream SC-x0 SCSI tapes do not support the
+ standard SCSI SASD command set and therefore need
+ their own driver "osst". Note that the IDE, USB (and
+ maybe ParPort) versions may be driven via ide-scsi or
+ usb-storage SCSI emulation and this osst device and
+ driver as well. The ADR-x0 drives are QIC-157
+ compliant and don't need osst.
