SMC2 is the first thing to disappear when using the parts I'm doing that, too. In fact, it's the default configuration for the TQM8xxL modules (all of them). The reason for that is that TQ uses the serial connector not only for SMC1, but also for RESET (on the RTS pin) and autoboot enable (on the DTR pin). While this is handy when you know about it and use the right cable, it has confused enough of my customers to avoid using it as a default :-( > for other data communication protocols or interfaces, so custom > software tends to assign these for other purposes.
