Description nicolls 2000-12-15 07:50:01 UTC

Recent Linux kernels use the /dev/ptmx to allocate ttys.  Some 
commercial software (such as the new release of Matlab) require 
this device to function correctly.  The device is not currently 
supported under FreeBSD, so the software doesn't run.

Assign to emulation@FreeBSD.org. It is not going to be addressed if 
it's assigned to me and I don't do it. Maintainership of the Linuxulator 
has been passed on to emulation@FreeBSD.org as well.

Does this problem still persists with a recent FreeBSD and a recent 
default linux base? 

Do you use the right matlab version (supported for RedHat 8 or Fedora 
Core upto 3)?

Matlab is modified to fall back to using traditional terminal devices 
if /dev/ptmx doesn't exists. So close this PR.
