Long overdue, you have to upgrade
even further now.

Dosemu doesn't like your /dev/ttyS2
for some reasons.
Try "setserial -ga /dev/ttyS2" and
compare it with "setserial -ga /dev/ttyS0"
to find out why.
Also you may want to add an strerror(errno)
to be printed along with the aforementioned
error message to find out what the error
actually happens.
Most likely your /dev/ttyS2 is misconfigured.
