TCP2Serial conversion or transmission problem.
I'm trying to communicate between a Tibbo em202 and my pc but I have one problem. I'm not sure if this is related about settings in em202 but I couldnt figure it out.
I wrote a simple program in VB6 for watching the communication between computer and tibbo, tibbo is sending TCP packets about what it gets from its serial port, and when I send something from the serial port, everything is fine, I can read it from the tcp monitor. And I can enter into serial programming mode with escape characters, my reception of serial port is also working, I can get the G** command results via serial port, but my problem is :
When I send something from my computer's TCP IP socket, I expect to have the string read from my serial port when the connection is already established. But that doesn't do like this and I don't see anything.
If you have some suggestions, that'll be great.
The sw i wrote is like this, one side serial, one side ethernet..

Inappropriate?Few place to check:
1. Make sure that flowcontrol is set correctly on both the EM202 and your software.
2. Maybe your program is sending the data to the wrong port?
3. Check DS Manager after you send the data from Ethernet to PC and see if under the "Routing Status" the Ethernet > Serial buffer has data stuck in it?

Inappropriate?Thank you. The connection was OK but the data reception procedure was incorrect in my software. It was looking for the break character to display the result but the em202 wasn't sending any of it. The problem is solved now.
I’m happy :)
