How to open/read/write a serial port with STk/Linux

I tried:

(define $inp (open-input-file "/dev/ttyS1"))
(define $oup (open-output-file "/dev/ttyS1"))
(write-char (integer->char 3) $oup)
(display (char->integer (read $inp)))

I didn't get errors but I didn't see any action on the serial port (I was
watching with a breakout box). Using Minicom I was able to see characters
going out and coming in. Am I on the right track or is there something
special about opening serial ports?

Any help and pointers appreciated.
