Exact RS232 settings used by Javelin IDE

tlhawkins

Hello,

I'm trying to connect to my stamp to program it wirelessly using 802.11
I have a gridconnect WI232 that handles the wireless transfer of data from my laptop to the Javelin stamp.· I have it setup where I can telnet into the stamp and get data from a running program so I know the connection is working to some extent.

However,· when I try to connect to the stamp with the Javelin IDE it can't find it.· I'm sure there must be some RS232 settings that aren't being handled correctly by the WI232 device.· There are a lot of options on that device,· I'm sure I could program it to do what I need if I only knew what I needed.

Does someone know the EXACT serial communications setup between the Javelin IDE and the Javelin Stamp when it's connected via RS232?

Thanks in advance,
-Travis

The javelin is programmed via a serial connection that uses
RX, TX and DTR. The baudrate is 28800.
There is a hardware echo: anything sent from the pc to the javelin
is directly echoed back to the pc.

The most likely thing that will happen when trying to program over a Wi-Fi module not design for programming BASIC Stamps is that you will have latency issues. This only happens when trying to program or identify. Just communication usually works, but timing is critical when identifying and programming and as Peter mentioned, required the DTR line to be controlled precisely.
