Read from serial port windows

Exchanging data multiple times A simple way to get more accurate data on the behavior of a particular serial port is to send the same command from your serial app to this COM port one more time. The differences between sessions can be shown automatically. Add multiple serial ports to one session. Work with COM ports of any type. Log and sniff serial data transmission. Record data in real time. Log both received and sent data streams. Divide the redirected file into parts or limit its size, depending on your needs.

Catch and analyze the activity of a software hardware connected to the monitored COM port. Copy saved data to the clipboard.

Exchange serial data in the full duplex mode. Use advanced tools with presets for filtering data streams. Customize filters in the toolbar. Filter data by ports. See the data that an app actually wrote to a serial port as well as the data that the app tried to write.

Keep on writing to the existing data with the command line option. Show 10 more options. The software solution provides: Simple and friendly interface. Digitally signed software and its internal drivers.

All values are in milliseconds. ReadIntervalTimeout Specifies the maximum time interval between arrival of two bytes.

If the arrival time exceeds these limits the ReadFile function returns. ReadTotalTimeoutConstant is used to calculate the total time-out period for read operations. For each read operation, this value is added to the product of the ReadTotalTimeoutMultiplier member and the requested number of bytes. ReadTotalTimeoutMultiplier is used to calculate the total time-out period for read operations.

For each read operation, this value is multiplied by the requested number of bytes to be read. After this you have to set the values using SetCommTimeouts function. Writing Data to Serial Port. Writing data to the opened serial port is accomplished by the WriteFile function. Here we are using the sizeof operator to find out that. I have interfaced a microcontroller board MSPG on Launch Pad to the serial port using a null modem cable like this.

The Controller waits for a character to be received and lights up the corresponding LED. The code for MSP is included in the zip file. Here is the screen shot of the Program writing into serial port. One way to do that is to use polling where the ReadFile continuously reads from the serial port and checks for any received characters.

Other way is to setup an event and let windows notify us when a character is received. We are going to use the second method here, following are the steps. Add your solution here. OK Paste as. Treat my content as plain text, not as HTML.
