G'day all,
Can any Mac people tell me why
FHandle := fpOpen(Port, O_RDWR or O_NOCTTY);
(Where FHandle is a longint and port is '/dev/tty.usbserial-A400379A')
.. just locks up waiting ? (I've tried it on two Mac PPC machines now, both cross-compiled from my
linux x86 install, and compiled natively on the MacOS box)
macppc:~/Pascal/Proploader user$ whoami
user
macppc:~/Pascal/Proploader user$ ls -la /dev/tty.usbserial-A400379A
crw-rw-rw- 1 root wheel 9, 2 Sep 23 14:45 /dev/tty.usbserial-A400379A
I can put O_NONBLOCK in there and it will open, but then I have all sorts of problems talking to it.
I really want it to block.
This works on Linux x86 and PPC, but this is the first time I've strayed into
MacOS land.

Obviously I'm doing something dumb, I just don't know how to debug it. No
strace on MacOS.

Brad
