There are other devices for other modes:
/dev/osst0l : c 206 32
/dev/osst0m : c 206 64
/dev/osst0a : c 206 96
/dev/nosst0 : c 206 128
/dev/nosst0l : c 206 160
/dev/nosst0m : c 206 192
/dev/nosst0a : c 206 224
I own a DAT tape drive which uses the standard st driver, the meaning of
the different modes is configured in /etc/stinit.def from the mt-st
package.
