#111581 - buffer/driver Responding to: ???'s previous message |
If you are conecting the uc to the RS232 port in the PC you need a buffer/driver like MAX232 to reach the mininum of +/-3volts required by the std. Are you using it?
Also you have to check the timings, specially if you are using the parallel port, because this are software managed. |
