Does the program just hang, or does it eventually (several seconds
later) give up and print an error message?
Try 'verbose' mode and post the results:
nqc -v -d test.nqc
One possibility is that somehow the port is configured for hardware
handshaking and that is causing the open() to block. You can check for
this case by adding a suitable printf in PSerial_unix::Open() (in the
file platform/PSerial_unix.cpp). Some other Unix variants (notably
IRIX) have some trouble with this...one fix is to change
if ((fTerm = open(name, O_RDWR)) < 0) {
to
if ((fTerm = open(name, O_RDWR | O_NDELAY)) < 0) {
I'm not sure why this matters...or why almost every other system out
there doesn't need the O_NDEALY...but its at least worth a try.
