How to work with COM port on a modern server?

Question

Serial port

Hello.
I own an Intel R2308WTTYS server, I needed to receive data from one old piece of hardware, which can only send them through the COM port. The server has 2 COM ports, 1 in the form of RJ-45, the second in the form of a connector on the motherboard. I connected a cable to the connector on the motherboard, turn on the piece of iron in it, open putty and it's empty. No data is coming. Checked:
1. A loop on a regular PC, everything works.
2. BIOS settings, Serial enabled.
I tried to connect Cisco ASA for verification, there is still no data.
What could be the reason?

Answer 1

Are the settings for connecting to the COM port in putty correct?
If the port is dead, there are tons of USB-to-serial adapters on the market these days. Were you able to connect to a piece of hardware from another computer via putty to make sure that it is working, and can you check the connection parameters on a known working computer?
