Hello World in the send box → Press Enter (or click Send). You should see Hello World appear in the receive window. If you see garbled text, your baud rate is wrong.Unlike the basic Arduino Serial Monitor, SSCOM separates the "Send" and "Receive" windows. This prevents the user from accidentally typing over incoming data and allows for a cleaner workflow. You can see the history of received data at the top while composing a new command at the bottom.
Most serial terminals let you send a single predefined string. Sscom lets you build an entire script of commands in a side panel. Need to send AT+CMGF=1, wait 100ms, send AT+CMGS, then inject a text message? Done. You can even set custom delays between lines. This turns tedious manual testing into a push-button affair.
