- javac Hello.java
- javac HelloImpl.java
- javac HelloServer.java
- javac HelloClient.java
- start rmiregistry
- start java -Djava.security.policy=policy Server
- start java -Djava.security.policy=policy Client
But in the second step I have this problem

QUESTION
I am writing an application that communicates with an AT modem (in this case with a conexant cx93010 chipset, see manual here: https://www.manualslib.com/manual/1140976/Conexant-Cx93010.html). My application collects callerid information and uses various ways to get information based on that (blacklist-website queries, information on extension, local whitelists and blacklists etc.)
I would like to take this a few steps further and transmit and receive voice data for numerous reasons, i.e. answering machine, detecting when someone with a suppressed number calls and then play a predefined message and hang up.
I have already set up an interface to talk to the modem and get the callerid data that I want, and hang up calls based off of that.
My question is the following:
As my application receives audio data, doesn't said audio(!) bytestream randomly(!) include DLE messages as part of the audio data?
I have checked the manual and other resources, and nothing tells me if that is the case, and if so, how this is being handled?
-Are those random occurrences being escaped? If so, how?
-Or is it that audio data is send in chunks of a fixed size (based on codec?), and in between those chunks, intentional DLE messages may appear, so that way I can ignore DLE character occurrences for x amount of bytes?
Various code samples found on the net (basically all I could find) just ignore this. I am wondering if they are accurate implementations or just quick and dirty examples to show basic function and these corner cases have been forgotten over time.
Thank you in advance!
...ANSWER
Answered 2019-Sep-11 at 04:05To close this up and especially because (at least to me) this already shows up in google searches up top, I would like to share the answer I have come up with myself.
So, random DLE-bytes that are part of the data stream ("data" meaning "payload", and not the raw data) are (according to the manual) escaped by appending another DLE-byte to them. So occurrences of two DLE bytes together means you need to remove one of them and that singular DLE is part of the data. If you encounter a singular DLE in the raw stream it means that the next character is definitely an event code sent by the modem (DCE) to you (DTE), except for:
The combination of DLE + SUB is used to escape two consecutively transmitted DLE bytes. This is done in order to not blow up the amount of raw data to be transmitted.
That means that various examples simply receiving and interpreting raw data as audio data and/or send audio data without escaping are just inaccurate oversimplifications.
Thank you to anyone who read my original question.

As I said in comment, you have 2 graphic objects in the same axes
which have to interpret their CData
in a completely different manner.
The first options I looked for was to modify one of the arrow3d
or rotateAxisTicks
so their graphic objects would be "compatible" (in the way the color data are interpolated on an axes), but it would be quite intensive and the aspect of the 3d text would have to be constantly monitored/adjusted for any other change in the figure.
So the easiest option is a classic MATLAB hack ... place your graphic objects in different containers (different axes
), then superimpose them on a figure, and match some properties (limits, view, etc ...) so they appear to be only one.
Here it goes:

Answered 2018-Oct-03 at 17:54Here is how you might convert this to use a PreparedStatement, which will also take care of a number of potential problems including preventing SQL Injection, and data type mapping of the values being inserted. I'd suggest you review the documentation on using PreparedStatements. In the meantime, I've included a simple example of how you might use a Prepared Statement.

When lighting (GL_LIGHTING
) is enabled, then the color is taken from the material parameters (glMaterial
).
If you still want to use the current color, the you have to enable GL_COLOR_MATERIAL
and to set the color material paramters (glColorMaterial
):
