I have some questions about rmt.

In bsd4.2 the maximum blocksize is defined as 10240 bytes, by
historical reasons (PDP). Can I increase the maximum blocksize?

What is the maximum blocksize for rmt on a Sun? I don't want to find
it out the hard way. 

Rmt uses the vax bsd4.2 "tape operations codes" from "sys/mtio.h",
as the communication protocol. Is it common that all systems has
the same operations codes in mtio.h? 

The communication protocol should be separated from the system
dependent mt operation codes.
