We are controlling a couple of furnaces via a Eurotherm 2416 with RS-232-C 
interface. I don't know if it uses the same protocol as the 2404 though, 
but our code might be a starting point for you.

The protocol of the Eurotherm 2416 includes BCC checksums, which Dirk 
Zimoch's stream driver couldn't handle at the time I wrote the EPICS 
support. As a result, our code is flat EPICS database of soft records with 
an snl program calling functions to send and receive messages to the device 
via a pseudo-terminal VxWorks device driver.
