Piece of cake,
1) From Apollo side:
rwmt -w <filename/directory name> -unlab -f 1 -dev ct
-rl <record length (i.e. 80 bytes)> -bl <blocksize>
2) From Sun side:
dd if=/dev/nrst8 of= <output filename> ibs= <blocksize above>
cbs= <record length specified above> conv=unblock
I choose 80 bytes for the record length since thats the usual size of
ASCII text files. A good number for blocksize is 512. P.S. - if I didn't
make it clear, record length and blocksize is entered as an integer number
only, don't use "80 bytes" for either system.
