Since I never use a simulator, I can't comment on the results but you need to add 'errors' to the #use RS232( ...options....) so the hardware UART won't lockup, freeze when more than 2 characters come from the PC.

This is probably the problem, no "errors". For the caps, I saw both options and the 2 caps on VS+/VS- were connected to ground, however on most examples in google, there was 1 cap with no ground.

I will test with this and see what happens. _________________ Yo! I love learning and technology! I just do not have experience so do not be angry if I ask a stupid question about a detail! From so much to remember sometimes I forget the details in order to remember the big problems! |

Since I can't do much to return the favour, if anyone needs anything with computers, ask! To solve a problem, say which is better and which is not, etc. _________________ Yo!
