Write a character to a serial port.
unsigned char __fastcall__ ser_put (char b);
Send a character via the serial port. There is a transmit buffer, but transmitting is not done via interrupt. The function returns SER_ERR_OVERFLOW if there is no space left in the transmit buffer.
- The function is only available as fastcall function, so it may only be used in presence of a prototype.
