I have a Wangtek 5099E 60 MB tape drive connected to a PC (QIC)-36
controller. The problem I have is that I can't use block sizes larger
than 4k. If I try larger sizes (to get the tape stream), no data are
transferred. I used the command
  dd if=/dev/rwt0 bs=512000 of=tape  
The command simply returns, but that's it.
Is there a more recent version of /sys/i386/isa/wt.c than that 
of July 92?
I want to write a driver of my own. Unfortunately, I don't have any
information about the QIC-02 programming interface and hardware.
Where can I find such info?
If there's interest I'll summarize.
Robert
