SGI - Mac
Ive made a set of routines to access serial communications. Its of the
basic "Open a port, write a buffer, read a buffer..." style, but now that
its abstracted it saves me from thinking about ioctl() anymore. I dont promise
robustness, but Ive used them for simple communication with a Faro Digitizing
Arm, and a servo driver.
Its making a lousy assumption about being on the second serialport on my indy,
you'll probably have to change the device.
Another set of code also works on a mac,
same API. Its not safe to use at interupt time though. Assumes modem port, but
its easy to change. I turn off all flow control, but at the least the code
is a reasonable example of useing the Serial Driver.
Note: The SGI software was IRIX 6.2. The serial interface has changed regarding setting
bps, and is wrong for 6.3-6.5. The change is trivial, but I haven't fixed it in
this code yet.
- Serial_OpenPort() - Specify baud, etc...
- Serial_Read() - no blocking
- Serial_ReadBlocking() - block until at least 1 byte is avail
- Serial_BytesAvail() - boolean return value
- Serial_FlushInput() - clear the input queue
