[comp.sys.hp] DAT Drives

   I am trying to access my HP DAT drive (1300S on a 375) 
from FORTRAN.  I can write records and read them, but 
I can't rewind the tape! The error I get is:

Illegal sequential I/O to tty attempted

   I can work around this by closing and reopening the file,
but my ultimate aim is to modify an existing program to
use the DAT in lieu of a disk.  It would be nearly impossible
to alter this program to use the close/open scheme.

   Any suggestions would be greatly appreciated.
