Serial ( COM ) Port Console Script. Received from the serial port.; Example: Read_Data. RS232_Read() returns 2 characters for each byte Loop%Read_Data_Num. Serial Communication with Node.js. Walk In The Woods. Python Call External Program Windows here. If you want to read serial data as ASCII. Send new data when it receives a byte of data in the serial port. I'm receiving data from a serial port in C. Reading from a serial port. Set an expiry timer loop doing the following read more bytes if you read 10.

Thank you for this very useful script. I marvel at the level of knowledge that it takes to create such a script. Until now I have not been able to get any terminal program that I have evaluated to behave exactly as needed in my application.

But, with the building blocks that you have provided, I have realized a proper configuration at last. The result will be incorporated in a computer-based system that provides magnification services to individuals with low vision. The script controls the the parameters of the display through the display's serial port. Again, my appreciation for this most helpful contribution.

Hi Ron1, Thanks for the compliment. I'm glad that you have found it useful and are putting it to such a noble cause. Well, necesity is the mother of invention. John Mayer All We Do Is Say Goodbye. It's funny that I was only about 26.4ms away from not developing this WinDLL version. For my application, I am using AHK to communicate with my companies ICs.

I first started using Port.dll and after several days of development I was finally at the point of where I should have been able to communicate with the ICs, however, I kept getting NACK (Not Acknowlege). I probed the Serial Port Tx line on the oscilloscope and noticed that there was only one byte of data being transmitted every 15.8ms - I was sending 8 bytes (8*15.8ms=126.4ms). It turned out that if our ICs didn't get all 8 bytes of data in 100ms then they timed-out and sent NACK. It took me about another 2 weeks to develop the WinDLL version. But to be honest, I couldn't have done it without the help of Lexikos. If I do say so myself, I've done some pretty amazing things with AHK.
