I'm working on a clojure web app that manipulates the serial
port. Well, uses it, anyway. The basic structure is to create a map
from web-visible names to devices accessible via the serial ports. The
problem is that Clojure and the serial port drivers don't seem to get
along very well.
I'm using the RXTX package (with class names in the gnu.io. hierarchy).
If I open the serial port as part of building up my maps, everything
works fine in testing, but trying to compile the uberwar hangs.
If I wrap the port opening and connection calls in a delay and then
force them when I actually need to use it, the first call fails to do
anything - seems like the .open returns before the port is actually
ready.
Similarly, if I restructure things to open the port before use and
close it afterward, nothing ever happens at all. It's been a while
since I tried this, and I thought at the time the problem was that I
was closing the port to soon; but looking at it now I see that the
open may be failing.
When I try running multiple actions through the port in a loop, only
the first one actually happens.
Yes, I realize only the first of these is really related to Clojure
per se, but figured I'd put them all out on the chance that anyone who
could help with the first one is probably familiar enough with the
RXTX or serial port IO in Java to help with all of them.
Thanks,
