I am using a Palm Vx running PalmOS 3.3, which means I have the New Serial Manager. According to the documentation, the New Serial Manager has a compatibility layer that allows calls to the older Serial Manager to function as expected. The problem that I can't seem to get past is that when you use the following statement to get the serial library reference number, it always returns with an error: sysErrLibNotFound error = SysLibFind( "Serial Library", &refnum ); Since the reference number is needed to make all other Serial Manager function calls, I can't access the serial port using Serial Manager function calls. Every example for accessing the serial port via the older Serial Manager functions has a statement like the one above, along with an error trap to abort if an error was returned. I would have to conclude that all existing applications that use the Serial Manager to access the serial port will not run on Palm devices running PalmOS 3.3 or higher. No one seems to have documented how to determine what to use for a library reference number for Serial Manager function calls on devices that have the New Serial Manager. You obviously can't use the above statement to determine it. Does the New Serial Manager not care what value you use for refnum? By the way, does anyone know of a phone number where you can talk to someone who can answer questions like this? The technical support people at Metrowerks all said this question was beyond their expertise, and I would have to talk to someone at Palm. I have been unsuccessful at locating any such contact at Palm.
