Is this by chance in a EEPROM device? Another possibility is that your UART driver/hardware configuration (cache misconfiguration?) is not seeing the UART "Tx ready" flag properly so that every time a character is sent to the UART it polls the UART flag for the maximum time, making the serial output extremely slow. > The beaviour you see is not normal, but without knowing your hardware > and your modifications to the code it is impossible to give any > specific help. > > As a general rule: version 1.1.2 is very old.
