Sounds like the RS-232 chip in the amp may be fried, especially if the PC com port it was connected to fried.
I’ve seen this in the public safety world. Lightning hit our phone lines coming into a PC at the site and took out every com port (multi port). Also com port on all equipment attached got zapped. Not sure what else. I do not own the KPA100 so cannot add anything else.
