SPTerm is a terminal use for communication between PC and a serial device. Newer version of window doesn't come with hyper terminal that allow basic serial communication through com port of a PC. SPTerm is developed to help me in part of my work that would need to check the communication with UART devices on my certain projects. The screenshot below show the main window of SPTerm
SPTerm will scan the computer for available com port in the PC. Setting for Stop bit, baud rate, parity and Bits can be selected before opening the connection to the port. When the serial port is open any data that is received will be displayed in the ASCII box while the Hex will be display in the Hex box. The check box Clear to send and Data Set ready shows the status of the 2 pins. Check indicate high on the pin while unchecked means that its low. Data can be send out through the text box at send group either using the ASCII or hex format. Checking request to send and data terminal ready would output high to each of the pins individually.
The screenshot above show an example of sending the data 0xAF 0xAA 0x31 in a loop back configuration. The data is received back and displayed both of the text box. The program SPTerm can be download at source code for the project can be obtain through the same place.
