guess the proper solution is to add it by udev rules<br/>
would recommen to google for it.<br/>
If you add a symbloc link sure you need to add after rebooting the system..<br/>

this does not work that way.</p>
<p>use only this<br/>
<strong><span><span>[SysCom]</span></span>Linux.Devicefile=/dev/ttyAMA</strong></p>
<p>and set a symlink in Linux for<br/>
/dev/ttyACM0 -> =/dev/ttyAMA1</p>

My CODESYSControl.cfg file is:</p>
<p><span>[SysCom]</span><br/>
Linux.Devicefile=/dev/ttyAMA<br/>
portnum := COM.SysCom.SYS_COMPORT1;<br/>
Linux.Devicefile=/dev/ttyACM<br/>
portnum := COM.SysCom.SYS_COMPORT2;</p>
<p>On port 1 everythink is ok. It is work, but I have problem with port2.<br/>
I can't even open this port.<br/>
