I am trying to use the SVAsync comport library. When it
installs an interrupt handler it tries to lock all
necessary stuff but it gives an error on locking
__djgpp_ds_alias.

I assume the error is due to the fact that __djgpp_ds_alias
is already locked. Is this true? (If so, where is it done?
I looked through the djgpp sources but couldn't find it.) I
noticed that when I try to lock something twice the second
time I get an error.

The dpmi functions seem to use an error variable named
__dpmi_error. Where can I find the meaning of its value?

Clemens
