----boundary-LibPST-iamunique-1038804875_-_- Content-type: text/plain Rainer, I believe the intent of Comm is for interacting with the Internet and not local serial ports. -Doug On 6/20/2011 8:00 AM, Rainer Neubauer wrote: Hi all, in subsystem Comm there is a Module Streams for serial communication. Two procedures of this module (NewListener and NewStream) take as parameter the name of the serial protocol to be used. The demo modules ObxStreamsClient and ObxStreamsServer show an example using the TCP protocol. Actually I don't really understand the intention of the module Streams. If it is to offer the same communication services using different protocols, how do I get it working with RS232 instead of TCP ? E.g. passing the protocol name "CommV24" to CommStreams.NewListener will not work, because CommStreams.NewListener looks for a service "NewListener" offered by module "Comm24", which does not exist. So, do I have to create a new module sitting on top of CommV24 and implementing "NewListener" and "NewStream" in order to pass the name of the new module as parameter to CommStreams.NewListener ? In my home project I'm currently working on I will have a serial communication to an external device. I would like to make the soffware adaptable to the type of communication to this device (TCP or RS232), because I then could replace the hardware device using RS232 by a simulator working with TCP.
