141 UART serial ports refer to 8250/16450/16550 series devices.
143 Older versions of the Linux kernel used this major
144 number for BSD PTY devices. As of Linux 2.1.115, this

230 225 = /dev/nst1a Second SCSI tape, mode 3, no rewind
233 "No rewind" refers to the omission of the default
234 automatic rewind on device close. The MTREW or MTOFFL
235 ioctl()'s can be used to rewind the tape regardless of
236 the device used to access it.

2797 The OnStream SC-x0 SCSI tapes do not support the
2798 standard SCSI SASD command set and therefore need
2799 their own driver "osst". Note that the IDE, USB (and
2800 maybe ParPort) versions may be driven via ide-scsi or
2801 usb-storage SCSI emulation and this osst device and
2802 driver as well. The ADR-x0 drives are QIC-157
2803 compliant and don't need osst.
