defaient Posted March 7, 2011 Share Posted March 7, 2011 Hi How can I use the serial ports? I've tried it using commg.dll but it's limited to 252600 (or something like this). I need to work with 921600 baud rate. Does it matter if my port is RS232 /RS422/ RS485? thanks! Link to comment Share on other sites More sharing options...

Does it matter if my port is RS232 /RS422/ RS485?thanks!The commg udf allows you to use any value up to 2000,000 but the hardware limitations might mean that high rates don't work. It could be that the udf has comments saying that only certain baud rates are allowed but that was only true until a couple of years ago.I don't know if RS422 or 485 work. If you use a RS232 to 485 adapter then I imagine it should work but otherwise I don't know. Maybe someone has experience with this. Serial port communications UDF Includes functions for binary transmission and reception.printing UDF Useful for graphs, forms, labels, reports etc.Add User Call Tips to SciTE for functions in UDFs not included with AutoIt and for your own scripts.Functions with parameters in OnEvent mode and for Hot Keys One function replaces GuiSetOnEvent, GuiCtrlSetOnEvent and HotKeySet.UDF IsConnected2 for notification of status of connected state of many urls or IPs, without slowing the script.

aion1987 Posted June 6, 2018 Share Posted June 6, 2018 Good day is the first time I write in the forum. I am using the commg.dll V2.83 and apparently I have a problem to establish comunicasion at speeds greater than 256000 baud. I am using the Putty program with which I was able to communicate at speeds of 921600 and 2000000. The IC also has communication to 115200 but this speed is not a problem. Has anyone been able to solve this problem? Link to comment Share on other sites More sharing options...

AutoIt as a language has grown by leaps and bounds in that time; what worked way back in 2011 may not work the same today.
