Sending a line of 21 characters to the port, I see only two trailing edges of CTS, which is consistent with receiving three characters by the SBC. The other characters are sent and lost. The SBC on the other end clears RTS immediatly after receiving a character. Linux may send one character at this moment, but that would be stored in the receiver buffer and the SBC only asserts RTS if the receiver buffer is empty. Instead it sends multiple characters, flooding the SBC.
