#92779 - Inverted? Responding to: ???'s previous message |
I think I know the reason of "_y"
You are getting inverted signal on Rx pin of the '51. "_" is what you get receiveing "A" inverted. "y" is what you get receiving <CR> inverted. I don't quite understand why you are not getting antything from "T" inverted, but that can really depend on your particular SW. I think the connection between the phone/modem's Tx pin and the '51 pin is incorrect. Can you check ii please? Jan Waclawek |
