microcontroller sends over UART (hex to dec) 1 0 2 0 253 when i connect the microcontroller with max202 to pc i receive the data correctly. but when i connect the microcontroller with ftdi FT232RL to pc i receive the following data: (hex to dec) 6 0 0 24 0 0 230 whats wrong? please see attached circuit diagramm. i always get this data so the communication itself seems to be ok.

Hello, I've been using FTDI IC's for so long and I'm sure I can help you with your problem. If you will sell boards with an USB-UART transceiver, I can even suggest you an alternative that is better cost effective that FTDI... Looking forward to help you on this task.

Your problem is one speed and/or Bits configuration problem, so I assume that the FT232RL is expecting that you send the bytes with some configuration and you are using another in your PIC, you have to see both datasheet and you go to find the problem. \The best option I can give you is change the PIC16f874 for PIC18f4550 and forget the FT232RL. If you want to use this device send me the source and I go to fix your problem for $50 in a day or less.
