serialpacket
SerialPacket is a net.PacketConn implementation over RS232.
It's designed to work with kcp-go to provide reliable transmission over LoRa or other noisy channels.
Test:
$ socat -d -d pty,raw,echo=0 pty,raw,echo=0
2022/03/27 22:48:28 socat[14099] N PTY is /dev/pts/5
2022/03/27 22:48:28 socat[14099] N PTY is /dev/pts/6
2022/03/27 22:48:28 socat[14099] N starting data transfer loop with FDs [5,5] and [7,7]
$ export PORT1="/dev/pts/5"
$ export PORT1="/dev/pts/6"
