It's possible, at least in some cases, to use SGI dial boxes on linux with
- Dial Box
- Power supply for the dial box
- Serial to USB adaptor
- admin access to the system, and awareness that messing around in
/devcan cause problems.
- add users to appropriate group for
- connect dial box and power supply
- create symlink
ln -s /dev/ttyUSB0 /dev/ttyS0
O, check if dials work.
