Is there some way of controlling the DTR signal of a serial connection in a CDP-application running on RTOS-32?

No, you can not control DTR directly in the current version (or earlier versions) of CDP.

What do you want to achieve ?

You can set protocol DtrDsr if that is what you want, or set <MultiDrop> to HalfDuplex or FullDuplex if that is what you want.

We are using a SerialStringDispatcher component for sending NMEA messages to another vessel over a radio modem.

DTR can be used to turn the radio modem on/off, and this is what we would like to do in our system.
