github.com/distributed/sers (go): Package sers offers serial port access. It is a stated goal of this package to allow for non-standard bit rates as the may be useful in a wide range of embedded projects.  This program opens a serial port, configurable by changing portname below and configures it for 57600 baud, 8 data bits, no parity bit, 1 stop bit, no handshaking. It then reads up to 128 bytes from the serial port, with a timeout of 1 second and prints the received bytes to stdout.
