### Accessing the Serial Port <a href="#toc150171916" id="toc150171916"></a>

Once the WiSer devices are connected, a virtual serial port will be automatically generated on your PC. Verify serial port in the Device Manager of your PC. You can access it through your preferred terminal software or even any custom software you've developed.

* Following example image shows the WiSer device detected in Device manager of Windows 10 PC

### Baud Rate Configuration <a href="#toc150171917" id="toc150171917"></a>

WiSer accommodates various baud rates to meet your communication requirements, whether they are standard or non-standard, with a maximum speed of 921,600 baud. Baud rate configuration can be conveniently adjusted within your terminal software.

By confirming that both the host system and the embedded device share the same baud rate, you can guarantee the successful transmission and reception of data in your wireless serial communication setup.

**Supported baud rates:** all standard and custom rates up to 921,600 baud

* Following example image shows the Baud rate configuration in TeraTerm serial tool.

### Flow Control Options <a href="#toc150171918" id="toc150171918"></a>

WiSer is equipped with hardware flow control, specifically RTS/CTS, ensuring a dependable data transmission process. To align with your application's requirements, configure your terminal software to integrate flow control. To activate RTS/CTS hardware flow control, press and hold the 'Find Pair' button for more than 2 seconds. This action triggers fast flashing of the CONN LED for 5 seconds, indicating the enabled status. Similarly, a prolonged press on the 'Find Pair' button for more than 2 seconds deactivates the RTS/CTS flow control, signaled by slow flashing of the CONN LED for 5 seconds. It's important to note that flow control is not supported for the WiSer WS-UU-EN variant.

**Supported flow control:** software (XON/XOFF), hardware (RTS/CTS), and None

* Following example image shows the flow control selection in TeraTerm serial tool.

### DTR Control Signal <a href="#toc150171919" id="toc150171919"></a>

WiSer also provides the DTR (Data Terminal Ready) control signal, which is crucial for call control in devices like data modems. It signifies that the terminal is prepared for communication. If your target embedded device supports DTR signal, then connect WiSer-TTL’s DTR to your target device and control it using your favorite serial terminal software or custom application. DTR control signal is not supported for WiSer WS-UU-EN variant.

* Following example image shows DTR configuration in Teraterm serial tool.

### Data bit, Parity, and Stop bits

WiSer provides configuring Data Bit, Parity Type, and Stop Bits settings from your favorite serial terminal software or custom application.

**Supported data bits:** 6-bit, 7-bit, 8-bit

**Supported parity types:** NONE, ODD, EVEN, MARK, and SPACE

**Supported stop bits:** 1-bit, 1.5-bit, 2-bit
