Well, then... However, if you open /dev/ttyS0 in tcl, and then do an
fconfigure on the fd, and you don't see the -mode in the response,
this tells you that TCL is not seeing /dev/ttyS0 as a serial device:
fconfigure [open /tmp/xxx w+]
=> -blocking 1 -buffering full -buffersize 4096 -encoding iso8859-1 \
-eofchar {{} {}} -translation {auto lf}
fconfigure [open /dev/ttyS0 w+]
=> -blocking 1 -buffering full -buffersize 4096 -encoding iso8859-1 \
-eofchar {{} {}} -translation {auto crlf} \
-mode 9600,n,8,1 -xchar {^Q ^S}
Someone else pointed out that maybe it is worth to recompile TCL
yourself for that platform in question.

This does not tell you anything about whether /dev/ttyS0 is the
correct path on your ARM platform.
