#USE RS232 issue defining STREAM - V4.120

Apparently you are supposed to be able to specify a stream id with the #use rs232 compiler directive.

Having multiple streams with a single uart is usefull because it provides a method of changing partity at run time... you simply select the appropriate stream with putc, getc, etc.

I get a compiler error when I add STREAM=1 to the use RS232 statement

USE parameter value is out of range "STREAM"

Any ideas?

Don't use integers. It has to be a symbolic name. You don't need to
have a separate #define statement for it. Just put the identifier in
the #use rs232() statement as shown below:
