Jim:
Here is the entire AppStart function, which came from the starter.c file provided by
Stationery for C, and which I have added to. I am using CodeWarrior for PCP R6. Keep
in mind that I am new to Palm programming. My goal in this test program is to receive
character via the serial port and display a count of the number of characters received.
static Err AppStart(void)
{
StarterPreferenceType prefs;
Word prefsSize;
Err err;
char error_str[31];
// Read the saved preferences / saved-state information.
prefsSize = sizeof(StarterPreferenceType);
if (PrefGetAppPreferences(appFileCreator, appPrefID, &prefs, &prefsSize, true) !=
noPreferenceFound)
{
}
err = SysLibFind( "Serial Libray", &refnum );
ErrFatalDisplayIf( err, "Serial library not found" );
if ( err == 0 )
{
err = SerOpen( refnum, 0, 19200L );
if ( err )
{
if ( err == serErrAlreadyOpen )
{
SerClose( refnum );
serial_port_open_flag = false;
}
}
else
{
serial_port_open_flag = true;
}
}
StrIToA( error_str, (long)serial_port_open_flag );
WinDrawChars ( error_str, StrLen( error_str ), 10, 110 );
return 0;
}

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 );
Show us more of the code. According to the line above you will not see
sysErrLibNotFound returned. Puzzling. Are you modifying the low memory
library dispatch tables? What is the code doing prior to finding the library? Did you
boot the device with the page-up key held down?
