ActiveSync over GPRS - Programming Request - Networking

Guys,
i know im not that great of a programmer. But i was wondering if anyone can program the following setup? it would help A LOT of us newbies .
- Serial Port emulator for PocketPC.
a. Input has to be transfert from a serial port (for use with activesync) to the internet service (TCP) with a specific IP-adress and back.
- Serial Port emulator for PC.
a. The emulator needs to listen to a specific port for TCP connection requests. And forward everything to the emulated com-port and back.
I know there excist many serial emulators for the pc, but none with an TCP/IP server integraded.
For a visual display, take a look at the picture that is included.

This is a very interesting thing. It would just provide ActiveSync over ANY TCP/IP connection (so also WiFi and such).
The serial ports part can certainly be done (not that I looked into how difficult it is, but I know it is possible)
I am however still unclear in how doing this would enable ActiveSync to work. Sure I can connect the PC side to a COM port, but how would this work on the PPC side? If I look in ActiveSync there, I don't see an option to connect to a COM port. Maybe I am overlooking something.

There are several USB-over-IP solutions out there, would they help in achieving your goal?? although its not clear to me what your goal is...
Hope this is helpful,
Cheers!

Activesync over GPRS - A fix remapping ip ports

I've been trying to get activesync to work with my desktop pc (which is on the net) for a few days now and it seems the main problem is that vodafone (and the others) block the required ip ports. The only reason they seem to do this is to force people to use other software or hardware (ie intellisync which uses other ports). This seems a bit unfair to me so I got to thinking. Move the ports that activesync uses to others which are not blocked. On the pc end this is easy (I used portmap - free software). Hoever, movi the port used by activesync on my xda2 hasn't been so easy.
Does anyone know how to either change the port activesync uses on the xda (either in a config file, hex edit???) Or does anyone know of a portmap type app that will run on the xda2? This way I can get this going (and vodafone can go to hell).

Lyndon.
VPN?
You can easily by-pass the problem by using VPN. Give it a try...
cool - never thought of that. I'll give it a go.
Thanks

Testing TCP Server on Pocket pc through ActiveSync USB

Hi all,
is there anybody who can tell me how i can test my pocket pc application which is a simple webserver, through activesync??
i can get it's IP address (192.168.55.101) but i can't reach it from my workstation, also i have no idea how to change it.
when connect through GPRS all works fine , simply would like to test it from my workstation.
After some research i noticed that it is a pass-through connection and that it uses TCP to do this.
anybody an idea on how to use it so that i can use my workstations IE to show the pocket pc's page on the little webserver i wrote.
greetz,
Marc

i have the same problem. if you find a solution please contact me by email at adrien dot joly at gmail dot com!
Folks, please do follow my articles. I've published several articles on the networking model of ActiveSync, particularly under WM5.
See http://www.pocketpcmag.com/blogs/index.php?blog=3&p=555&more=1&c=1&tb=1&pb=1
Under WM5 / WM6, as long as you don't disable the new AS networking model (it's enabled by default), your IP is 169.254.2.1

PC<->PPC application comms concurrently with GPRS conn

Hi,
I am trying to develop an application with both PC and Pocket PC components.
The PC and PPC need to exchange data whilst the PPC (eg XDA) has an active GPRS connection.
I first tried using evc and RAPI to allow the PC and PPC components to talk to each other. However RAPI relies on ActiveSync and it seems you cant have an ActiveSync connection to the PC (eg over USB) at the same time as a GPRS connection.
So
1)Am I right that ActiveSync at same time as GPRS is impossible? (And hence RAPI...)
2)What is the easiest way to do PC<->PPC comms without ActiveSync, on the widest variety of PPC devices?
3)Is there a way to do this without writing PC and PPC sides for all of
i) Bluetooth
ii) USB
iii) Serial
It seems like a lot of hardwork to reimplement all these, but some models have BT, some only USB etc etc
Any help appreciated...
Regards,
Giles.
hey,
im also trying to write some client -> server software for my mda/pc. Ive managed to narrow it down to two technologies (excluding activesync cos it needs to be portable)
- Web Services
- Client Server Model (tcpclient and tcplistener)
webservices are good as they will run on any net connection with port80 open, pretty fast and versetile but have some bad flaws. u need some back end data store (like a mysql database) as data is not persistant on then... also u cannot "push" from the server to the device (this may or may not be an issue)
the tcpclient model is starting to appeal to me in a number of ways. u can define your own light-weight protol (SOAP has a nasty habbit of bulking the objects out and GPRS costs!)... i started to write some little test apps and so far its looking good. Ive wrote a very tiny server that runs on windows and has a thin client running a threaded tcplistener and a mysql backend datastore. The test mobie simply constructs a tcpclient object and writes a string "hello world" to the port, which the server picks up and displays in a messagebox... so far this concept is working really well, and i have more control over the serialisation and communication of the objects and types.
i hope ive helped u in some way hehe

RDP going me crazy!
I install Remote Desktop Mobile on my Xda Trion,setup my PC(i hope so),and trid to connect,but...nothing
I have Huawei MT882 v2.0 ADSL modem,on my WinXPpro.,and I must setup static IP address and forward port(http://www.portforward.com/english/routers/port_forwarding/Huawei/SmartAX-MT882v2/Utorrent.htm) because of uTorrent.
When I tried to connect to my PC with address 192.168.x.x (or 5.129.252.10)Remote Desktop Mobile return me: Cannot connect.Likely reasons are: 1. The remote computer...
I wonder,what should I do,to make this thing work?
Which IP addres I should use,do I must install Remote Desktop Web Connection from Add/Remove Windows Components/Internet Information Service/World Wide Web Service,...should I forward some ports,NAT,what add in Select Remote User...WHAAAAAAAAAAAAAAT!!!?
PS I tried with Hamachi!Unsuccessful!Also tried VNC,Logmein
Please help!!!
First of all this forum is actually about HTC telephones and windows mobile.
But to answer your question :
You first need to make sure the router is setup to forward port 3389 (RDP port) to your ip address of the pc which you enabled RDP on.
Next thing to do is check if there is a seperate firewall (software of hardware) which could interfere with communication. Keep in mind port 3389 must be open to accept connections.
As a general rule it is not advisable to post your ip address to the public like this , esp if your posting about RDP, beacuse RDP will open your pc to the world.
Good Luck !
BTW , google is your friend.
Re:
Thanks for the answer,and advice!
I agre! It's not realy smart from me to public my address!!!
But!
I'm desperate(housewife)! )
Do you know,how to forward port on my ADSL modem,and which address i should use?
I tried all this with disabled firewall!
What is with Remote Desktop Web Connection,should I install it?
Googling almost 5 days and nights!
Xda Trion=HTC TyTN
As i don't know ALL ADSL modem in the world , i will try to explain it.
You should not need to install the web connection , this is only needed if you want to make a webpage which has an option to use the RDP inside the webpage.
Most routers/modem have a web interface. You can get into the interface by entering the ip addres of your router into a webbrowser. As you already setup port forwarding for Torrent I thought you already knew how to do this.
Once inside the webinterface , you should look for port forwarding / nat translation or similar. There should be an option to add a port forward.
Add as outside (internet) and inside (your network) port 3389 and TCP as protocol.
Next you need to know your local ip address. You can get this with opening a command prompt and entering ipconfig. The ip addres is usually something like 192.168.x.x (x is a number)....
Add this number to the forementioned line and you should be good to go. Apply the port forwarding (sometimes it's needed to save the settings to get them applied).
Blody Huawei MT882v2.0
Before my current ISP(Telekom Srbija) I use Neobee ISP,and with Neobee I didn't know for port forwarding etc.
Everything was Plug&Play,like it should be!
My torrent work for straight A,DHT status in torrent was green like Greny Smith apple without port forward...Those Were The Days...
On some Serbian forum( http://www.elitesecurity.org ) I find useful( i hope ) thread about port forwarding, and i hope that my Chinese sh.. modem Huawei can handle 2 port forwarding at the time, and also hope i don't screw my formerly port setup!
I write, if success!!!
Thanks P.
go to your router, and click on "port forward" tab.
port: 3389
protocol: both
ip address: 192.168.1.140 (based on your screenshot)
also need to enable "remote" on your Xp or Vista, and must have a user with password logon.
Forward port 3389
I just forwarded port 3389 on my Huawei MT882!
Nothing happened!
All same shi...!

Some ideas???

Use LogMeIn free instead i#d say, its really simple to use and much more secure.
LogMeIn
I'v downloaded LogMeIn free,create account,bla-bla...
When I log in,somewhere on the page i read something like... three more try...
What's the catch?
Link,how to,etc...???
Thanks in advance!
There is no catch I've been using it for over a year with no worries, you might have signed up to try out pro version. But after that's finished will revert to free.
