I recently bought a Home Theater Master (now URC) MX-1000 remote.
This remote is 20 years old, and needs to be programmed via a serial cable. I have an old PC running on Windows XP with two serial ports.
I installed the MX Designer software, and configured the serial ports as indicated in the manual (COM 1, 115,200 bit/s, Xon/Xoff, etc.), but I am unable to download a program to the remote. I am getting a message that says ‘’DOWN LOAD FAIL!’.

Does anyone on the forum have any idea?
Thanks in advance.
