When I attempt to use my TREO 300 to access my work dial-in connection (AS5200 PPP dial-up), I get an immediate failure:

Fatal Error
DataMgr.c: Line 7025
DmWrite: DmWriteCheck failed

Following this, I have to reset. Conversions with various Sprint techs seemed to conclude that Sprint has stopped offering PPP dial-up and may or may not add it again.

Does anyone know anything about their plans or the validity of this conclusion? Thanks.
