...StampPlot recognizes the
txtMinA
command:
...accepts data arriving on the data port and stores it as a decimal value. Execution will
cease until serial data arrives. Another way to accept arriving data for above would be:
...where the parameters are:
While this looks more complex,
connected, or if there were other communication problems, your program would not sit
idle endlessly waiting for data. This is usually an undesirable situation in a process
control scenario! Depending on your needs, either may be used.

When using DEBUGIN, it is important to begin the program with PAUSE 1000. Placing
PAUSE 1000 in the Initialization section ensures that the COM port connection is stable

that never arrives. If the BASIC Stamp does appear to hang – no sign of data arriving –
