@avra is correct: you want to make sure your device can support Modbus ASCII if you’d like to use a Terminal to attempt to poll Modbus registers. However, even using Modbus ASCII protocol takes some Modbus experience, and even if you know the unit ID and registers you’d like to poll, you will need to calculate the CRC for the message.
Could you add some more detail on what you are hoping to accomplish?
Also, here’s some light reading on Modbus RTU vs. ASCII: http://www.simplymodbus.ca/ASCII.htm
Good luck!
