Is there a an RX Buffer?
I am trying to receive 5 bytes from a device but after I use getc to read the first byte the serial becomes unreadable. Is the buffer only one byte? Do I need to turn on the buffer or make it bigger? I am using a Nucleo F401RE and serial 6.

Serial uses no buffer except the hardware buffer. BufferedSerial (search for it) does implement a buffer.
I don't know how much of a hardware buffer the F401 has, but it shouldn't matter as long as you can handle the incoming bytes faster than new ones arrive.
Hi Taylor, I have the same problem, how did you fix it?
