[fpc-pascal] Serial port access on Darwin PPC

[Brad Campbell]

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.

Free Pascal Compiler version 2.2.3

Compiler Date      : 2008/06/14
Compiler CPU Target: powerpc

Supported targets:
   Linux for PowerPC
   Mac OS for PowerPC
   Darwin for PowerPC
   NetBSD for PowerPC (under development)
   MorphOS
   AmigaOS for PowerPC

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

Regards,
Brad
