Hi:

I found this same problem when the serin command does not get
what it is looking for. If the strings do not get to the SERIN in the right
format, then the serin just hangs up the PIC. The PIC is waiting for the
correct number format.

for example.

SERIN PortC.0, t300, [170,170,TempIn]

if the numbers 170 are not transmitted, or arrive correctly, the PIC hangs
waiting for the correct "strings"
