How do I write to a serial port? I'm on Linux, and want a baud rate of 115200.
I'm new to Scheme. I can't seem to find a library to do what I want.

Ah, OK. It seems fairly straightforward:
(system "stty -F /dev/ttyACM0 115200 crtscts")
(define out 0)
(set! out (open-output-file "/dev/ttyACM0" #:mode 'binary #:exists 'append))
;(set! in (open-input-file port-name #:mode 'binary))
(file-stream-buffer-mode out 'none)
(write-byte whatever out)
(close-output-port out)
(define out 0)
(set! out (open-output-file "/dev/ttyACM0" #:mode 'binary #:exists 'append))
;(set! in (open-input-file port-name #:mode 'binary))
(file-stream-buffer-mode out 'none)
(write-byte whatever out)
(close-output-port out)
