Ah... I see the problem now. And it's not with your code, it's a bug in Palm OS 4.0 --
probably not what you wanted to hear, huh?
This has been fixed in Palm OS versions after 4.0, and I've already written an
internal 4.0.1 System Update which fixes the bug. But unfortunately, we have no plans
to release it for all existing 4.0 devices due to a lack of available testing
resources.
The fix is rather complex, because it has to patch the serial manager's SrmControl
trap and pass the srmCtlRxEnable and srmCtlRxDisable opcodes down to the current
serial driver plug-in. The ROM version of the routine in Palm OS 4.0 does not pass
those two serial opcodes down, which is why you see the serErrNotSupported error
returned from SrmControl.
If you feel this issue is serious enough to warrant the release of a System Update to
correct it, lobby Palm developer support to provide the required Q/A resources to make
it a public release.
