Re: SMC2

Oh oh......are you using an 823 or 850?  Sorry about this, you will
have to change the code.  Someday, I have to finish up a better UART

as a UART.  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.  I seldom see anything
but SMC1 used for a UART, so making the driver better hasn't been
high on the list......
