Anyone has ideia of what can be wrong with this?

I'm getting a bit worried about the serial there any way to check
if it is ok?
Back in the 90s a DOS program called Check-IT existed. Among others it had the capability of checking the operation of a serial or parallel port. You could even solder (buy?) a loopback connector which basically crosses lines so that anything sent to the port will loop back to the sending machine. That way automated tester application could test various RS-232 lines (RX/TX, CTS/RTS, DTR/DSR) and various baud rates for correct operation. At the time I actually could rule some of the tested ports being broken. However, most ports ever tested were ok and problems were somewhere else.
