MSComm control input property
Posted on 1997-08-25
I want to use the MSComm active X control to get some data from a serial device. I know that the device is sending me data because I have another device that lets me look at the data comming through the serial port directly, therefore, the availability of data is not an issue.
I have defined the input buffer to be of 1000 bytes. I also defined the inputlen property to be 0 so that I can read the entire contents of the buffer at once.
Here is the problem: when I define the input to be text, the input property only retrieves a few characters from the buffer eventhough I know the buffer has 1000 characters by looking at the inputbuffercount property. The number of characters retrieved vary from 1 to 9; no more, no matter what I define the inputlen property to be.
If I define the input to be binary, the input property only retrieves half the buffer, no more, no matter what the buffer size is.
How can I retrieve the whole buffer?
P.S. By the way, my settings are 9600,n,8,1
