SCI access (BDM vs. Serial Monitor Programming)

Hi,

 

I want to set up a demo for SCI access for my students on a 9s12c32 board (Tech. Arts Esduino).  While I can use a BDM, they're using the onboard serial monitor.  When programming from a P&E BDM the SCI port will talk to a terminal program on the host computer (Win XP using RealTerm or HyperTerminal).  However, when I try to load the same code onto a 9s12c32 via the serial monitor almost nothing appears in the PC's terminal application (except hex F0) and then the code appears to hang on the 9s12c32.    I tried a sample code from Jon Valvano (http://users.ece.utexas.edu/~valvano/Starterfiles/SCI_9S12.zip) including some variations of my own and they all seem to have the same problem. 

 

I'm using the serial monitor availabe at Tech. Arts: http://www.technologicalarts.ca/support/docs/Esduino/Code/SerialMonitor/UseWithHiwave/ESD12C32_Serial_Monitor.abs

 

Any suggestions on how to resolve this issue?

 

Thanks!
