I have a device that sends data to Hyperterminal. What I want is that when a certain piece of text appears is to get an alert, either audible or visual. Is there any software/scripts etc available that might of that functionality?
You'd probably be as well using vb .net or similar and listen to the device using the comms port directly. You can then trigger an event based on the returned data.
There's some useful info here:

I want to build something with Raspberry Pi Zero and write in Go,
I never tried bluetooth before and my goal is;
Sending a dynamic packet which it will change every second, an iOS app will expand this message and with a button, client will send a message back without a connection.
Is Bluetooth Advertising what I am looking for and do you know any GoLang library for it? Where should I start?
There are quite a lot of parts to your question. If you want to be connection-less then the BLE roles are Broadcaster (beacon) and Observer (scanner). There are a number of "standard" beacon formats out there. They are summarized nicely on this cheat sheet
Of course you can create your own format as these are using either the Service Data or Manufacturing Data in a BLE advertisement.
On Linux (Raspberry Pi) the official Bluetooth stack is BlueZ which documents the API's available at: https://git.kernel.org/pub/scm/bluetooth/bluez.git/tree/doc
If you want to be connection-less then each device is going to have to change it's role regularly. This requires a bit of careful thought on how long each is listening and broadcasting as you don't want them always talking at the same time and listening at the same time.
You might find the following article of interest to get you started with BLE and Go Lang:

How can I catch this output logs by using Delphi ?
On picture is my cellphone, but it could be any other modem. I need to get the result form "Query Modem"
I want my program be able to make query such modem and get the output logs.
update question:
I want to see that kind of logs (not exactly same) by using any possible way. It is okay if need to dealing with com port component. My concern is the result from ATI1
You can connect to the modem via your com port.
Use something like Turbo Power's Async Professional (free, open source).
http://tpapro.sourceforge.net/ApdComPort.html
Send the AT commands that you need, and catch everything that the modem returns.
I have been using Windows APIs for NFC communication. I am successful in getting and sending NFC messages from Windows PC, using a local console app. However, I want the communication to be done using a Windows service. Here is what I have:
A C# plugin (DLL), which makes the API calls.
C++/CLI Wrapper that allows unmanaged C++ code, to use the above plugin.
A C++ plugin, that the service will load (this is a requirement, it has to be a plugin)
If I load the C++ plugin into a local console app, and run, it can catch all NFC events (NFC device arrives in proximity, departs from proximity, can read and write to it). But, when I use the same plugin with a service, it is not able to catch those events. I can clearly hear the ping sound that comes when an NFC device comes close to Windows PC, however, none of the event handlers are called (For device arrival, device departure, read or write).
I also tried impersonation thinking that perhaps the context of who calls the method might result in blocking of the events. I could impersonate local user on the service, but the results were the same, no events could be identified.
Is there a reason why I cannot see any NFC events from a service, where as a local console app can get all of them? Again, I am able to hear the ping sound signifying that NFC device is close to Windows PC, but there is no handler getting called for it, suggesting there is blockage of something. Any ideas of what is going on?
Appreciate your time guys!
I am trying to find a solution to monitor the traffic (in and out) through a specific port. It is not required to capture the packets, or do anyting else. What it does is to be a traffic listener to make sure there are messages sent to or received from this port every 10 minutes. It has to be running at the background all the time (like a daemon), and without significant performance impact. Based on my research, one choice is to use an existing tool to do that. There are a bunch of tools out there to monitor or sniff the traffic, such as wireshark. Well, seems most of them monitor the traffic passing through a interface, instead of a port, or they can't run as a daemon. Another choice to write a program to do this. SharpPcap seems to be a good choice, but I still need to capture and analyze the packets to know whether such traffic exist. Could somebody suggest what I should do?
SharpPcap handles packet capturing in the same manner as Wireshark, so you can set filters to limit the packet being captured to a specific port the same way in SharpPcap as you can in wireshark. Except, SharpPcap will be a much lighter weight option vs wireshark.
Download the SharpPcap source tree and look at the Example05.SetFilter.
To narrow down the results so you capture only the packets you want to see you'll need to employ a few filters.
Pcap uses a common language across all applications that use it do specify the filters to set. Capture programs that use winpcap (windows) or libpcap (*nix) include, sharppcap, wireshark, pcap.net, winpcap, libpcap, tcpdump, etc... For a great resource on how to use pcap filters see this link.
Here are the filters you need:
ether host ehost
port port
Where the ehost is the MAC address of the computer sending/receiving the packets and the port is the port you want to monitor. So the full filter string would be.
SetFilter("ether host ff:ff:ff:ff:ff:ff and port 60");
The MAC and port here are for illustration purposes only, you'd obviously change them with the values that pertain to your specific setup.
This, used in the SetFilter example will simply print out a line of info with the time of when the packet was captured to the command line every time a packet is captured and meets the criteria if your filter.
If you want more detailed info about the packet, such as info from the headers or the packet's payload, you'll need to parse the incoming raw packet. Be sure to ask for help on the sourceforge project's forum if you need some tips on how to do this. The project developers are very active and always willing to help.
The best way that will limit the impact your tool will have on performance is via an ETW (Event Tracing for Windows) Real-time Consumer (i.e. a tool that activates an ETW trace and reads it immediately instead of saving it to a file). This MSDN sample is a great way to see how to do this via C# and it gives you some code to get started.
My son has a MacOS 9 box to which he is sending remote AppleEvents from his Leopard-based MacBook. Is there any way, programmatically, that I can send remote AppleEvents via TCP/IP from my Windows 7 Toshiba?
If it helps, apple events are sent on port 3031 via TCP/UDP.
From the high level, there are four pieces to apple events:
The data aggregation API (data requests are put into an opaque in memory structure). This API as it stands was wordy and painful to use. Thank goodness you have access to languages that have better data aggregation tools
Conversion/serialization - the opaque data structure is turned into something that can be serialized and transported to another process and for same machine events, this may be a null serialization
Transport the data is transported from one process to another. Single machine is probably just enqueuing a copy of the data. Remote machine is transport over a network protocol, which could be TCP/IP (but it works with AppleTalk as well) and may require authentication.
Deserialization/Conversion
You will most likely need to do steps 2, 3, and 4. If you don't care about getting any information back, you can skip 4, since one of the flags in a sent event is "no reply".
There are a relatively small number of types in the AE data model. I would write code on your OS X machine to send each and every type and reverse engineer the packets when they're sent. To speed up the process you might want to use appscript, on the OS X machine which will let you send events from Ruby, Objective C, or Python.
Sniff the packets between the MacBook and the MacOS 9 box using something like tcpdump or Wireshark. This will tell you what an AppleEvent looks like on the wire.
Then replicate those packets using your programming environment of choice on Windows.
I suggest wrapping up the code that you write into a library that you can reuse in other applications.
Good luck - this might be quite tricky!!
