|Description||specifies the type of half-inch tape drive being used.
"Pick-style" tapes use an 80-byte tape label. "Microdata-style" used a 50-byte label.
|Options||c Sets Cipher-type half inch tape. This puts the tape drive into start-stop mode, allowing the Cipher tape drive to properly sense end-of-tape. Cipher tape drives can run in streaming mode (the "k" option) provided that it does not stream past the end-of-tape marker. This causes the tape drive to get an end-of-tape error which can be cleared by turning the tape drive off and back on again.
k Sets Kennedy-type half-inch tape. This allows the tape to stream when searching for end-of-file or end-of-tape.
m Microdata format. This sets a flag is set in the TCB (tape control block) so that all subsequent tape reads will be performed in Microdata format.
p Pick format. This resets the "m" option.
