I'm working on a driver for a USB to serial device. I based my work on the AppleCDC sample code. Everything works great so far. Now I'm trying to print to a serial printer using the cups & gimp printing framework. I'm select my serial port in the Advanced Device List of the Printer Setup Utility. For some strange reason the device URI is fax://dev/myserial. When doing the same on a machine with a build in serial port I get serial://dev/modem. When I manually change the URI to serial I get a permission denied error when the port gets be opened. Here are my questions: 1) What do I need to do to get my device to identified as a serial instead of a fax device. What kind of call is the cups driver making to the device to determine this? 2) Any idea why I can not simply change the fax:// URI to serial://? This email sent to site_archiver@lists.apple.com
