The only flavor of UNIX for 286 currently shipping with a program
allowing DOS operation is V/AT, from MicroPort, with an extra-cost
package called DOSmerge/286 to run one DOS session. My experience with
this is that you should wait for a later release of this, since there
are some problems running serial ports in v2.2, and the three people I
know who have DOSmerge indicate that operation is still not production
quality. Other systems are being advertized, but I haven't seen a
production copy (as opposed to beta software you pay for) of anything
else. 

If you need to run ethernet connections, Xenix supports Excelan packages
which allow telnet and ftp. NFS is not supported at this time, and there
are some problems with PC-NFS holding interrupts off for 2-3ms, causing
lost serial data, etc. The C compiler is not PCC, and the object format
is not COFF, but you can product DOS executables if you wish.

Vexix (from Venturcom) is a certified port of SysV, and also supports
Excelan packages. This is a realtime version, with kernel fixes allowing
realtime operation. It appears to be a proper superset of SysV, and
should run any SysV program. Programs from MicroPort V/AT should run on
Venix.

Hope some of this helps.
