<p>1) Serial ports are almost never used these days so it's likely
no one is able to test your code. </p>
<div class="moz-forward-container">
<p>2) Your description of what you want to do is very confusing.
Please remember that computer translators don't work very well
for technical documents. <br>
</p>
<p>3) Jussi is right. You close the port before you read from
it. Of course there's nothing to read.</p>
<p>4) You are getting stream errors, that's what 'cannot write,
stream closed' is.</p>
<p>5) Obviously, for stream to be closed, your open failed. Your
program never tests for a successful open.</p>
<p>6) Open does not raise an error because your open code says not
to: Try SComm.Open(). With the Try, Catch will never be called.</p>
<p>7) In serial programming, direct reads from tty are best
event-driven. That way you can control the size of the buffer.
Oh yes, remember to remove read data from the buffer.<br>

bad them<br>
<br>
Explain that the main module is where I call the functions (I
see the translator didn't place it very well), and once of thems
are the close port ("$printdev.cp")<br>
<br>
I was must to read the English part before sent it, it is very
badly translated, EVEN IF I REMOVE THE LINE THAT CLOSES THE PORT
THE PRINT LINE DOES NOT OUT NOTHING, you can notice that it
doesn't write anything when I try to print.<br>
<br>
I noted that many of the gambas forums are very dead, and only
the gambas german book are alive, gambas resources are very
limited, and i must finish hurry my requeriments so from any of
you must understand when a people has some pression, i note when
herbert said that want to swicht to python and i understand
their problem.. it's the obvious result due the very limited
resources.. i like to continue work with gambas but please dont
make "too easy to do" (i pretentd to are sarcastid)<br>

<div>Not sure about that, but you certainly are the only
one who do not know how to use spell checker or care
enough to write understandable English.</div>
<div>At least one problem in your code is because you
close the stream and then try to read from it.</div>

<div>hello, today I have another
case, I want to implement
inheritance to the common code
with the serial port printing.<br>
<br>
What I want to do is to have the
procedures to open, close and
write to the serial port in one
class, and two others that
inherit these functions, then
one of the inheritors writes "A"
to the port while the other
writes "B" to the port but the
writing functions should be
called the same... <br>
<br>
</div>
i attached project with minimal
comments hope someone will help
with this!<br>
<br>
</div>
the firts problem its that i
received "'canot write "stream are
closed" why?<br>
<br>
</div>
the second problem its that i cannot
got any stream event when i do not
have stream errors<br>
