Hello All!

problem:

sometimes one of the lines on the bbs gets stuck. the caller exits, the bbs
sends the line back to frontdoor, which can't initialize the port any
longer

Solution tried:

a) all softwares I could get my hands on to reset the com port. But
there aren't that many to begin with, since the dos once usually don't work
under os/2 and when they do run, they don't do a thing.
b) write my own
I tried the library provided with speed pascal 1.0  - no way
I tried the GIO2 library provided with GNU EMX 0.9a - ditto

Then what ?

The more I look at it, the more I am convinced that the problem comes from
the fact that all those libraries, sooner or later, go down to the
devioctl() of the os/2 API. And the api won't let you touch the port if it
is used by another application. the problem is that the other
"application" is non existant.

I guess I have to go thru os/2 defenses and get to the port no matter what.
This was quite easy under dos, not quite so under os/2. I have localised in
the emx library a _portaccess() function in the sample program HW_IO, but
I'll be damned if I understood what it was exactly and how to use it.

So if anybody can shed any light on either:
a) the _portaccess(): what is it, how to use it exactly
b) how to increase the priority of my program to make sure it dos get
access to the com port - this may be passing from ring3 to ringsomething
else if my understanding of os/2 is correct (which it probably isn't, since
I am by no means a professionnal programmer)

Thanks in advance.
