I am having trouble reading information collected from a scale connected to COM1: (Windows XP Professional). There is no problem writing data (the fputs statement works fine).

But the fread do loop sits and waits. And waits, virtually tying up all resources on my computer and never populating the cScaleweight variable.

If I remove the do loop and just try to read one byte using only the fread(nHandle,1) statement, I get a timeout error. Microsoft Picture It Photo Premium 10 By Wcpo. How does one read serial data directly coming in the COM port without having to purchase an add-on library?

* Open Connection to scale nHandle = fopen('com1:9600,n,8,1',2) =fflush(nHandle) * Send Command nRet = fputs(nHandle,'GIVE_WEIGHT') =fclose(nHandle) * Read Result nHandle = fopen('com1:9600,n,8,1',0) cScaleValue = ' do while true cRead = fread(nHandle,1) if cread = chr(13) exit else cScaleValue = cScaleValue + cRead endif enddo =fclose(nHandle) Thanks Ron.
