So the last write that 'succeeded' was the cr to get a prompt back and we actually got the prompt? My guess is that your 'cfmakeraw' isn't setting everything up entirely right and the serial port is actuall translating the <cr< into <cr<<lf<.

What is reported by stty -a < /dev/ttyS0 (or whatever your serial port is). Here is what my serial port is set to right after reinstalling hijack.

$ stty -a < /dev/ttyS0
