thanks for this Gary, explains a lot... I'm basically writing from our current clients' hotel booking system into the Vingcard room key writer. But I haven't got the writer yet, so I was trying to get ahead of the game and just write via serial to another pc or something. I have the byte-stream that the periphery device will require, now I just need to send it to it! I could see if was 'barely' a CF invloved task, but you lot are all just so damned smart!!

It you are looking at a Web page writing to the serial connection on a CLIENT machine you are going to need a plug-in of some kind (ActiveX or Java). And it really has very little to do with CF (other than CF being the mechanism to deliver the HTML markup that causes the plug-in to be downloaded or activated). JavaScript sandboxing will stop you writing to local devices (like drives and comm ports) - unless you are running a HTA under Internet Explorer (then all the FileSystemObject stuff works and you MAY be able to fudge a FILE connection to the comm port that way). You will never be able to write directly to a comm port on the Client machine from a Server - again unless you actually have a plug-in that opens a socket connection back to the server and uses some type of streaming from the Server back to the Client that then writes to the comm port. This will still be Java or ActiveX on the Client machine - and you will need some type of socket connectivity on the Server side (under CFMX this would also need to be Java as CFMX doesn't have native socket support and appropriate threading to handle this....... yet...... watch out for Blackstone - apparently). Even so, this is not writing "direct" - it's using a Proxy on the Client side to do the writing for you. BTW - I dont think you have said yet what you are trying to do. That may help as there may be a completely different solution that someone has developed that may not involve writing to the comm port at all.
