I'm unclear here; to what specifically is "this information" above 
referring?

You describe the operation of an HP product, but the program on Jeff's site 
isn't an HP product.  The source starts off with:

*              TIME-SHARE BASIC DRIVERS AND MONITOR
* 
*                         KILE B. BAKER
*                         JOHN S. SHEMA
* 
*                      DATA RECORDING CENTER
* 
*                    MONTANA STATE UNIVERSITY

...and it appears on HP's LOCUS ("Library of Contributed User Software") 
tape as items 22255-60001 and 22255-60002.  So we're speaking of two 
different products.

HP BASIC might, but the MSU BASIC under discussion won't.  See, for 
example, the "CHIN1" routine in source file 6:

      LIA 0        LOAD CHARACTER
      [...]
      OTB 0        NO, OUTPUT TTY BOARD COMMAND
      STC 0,C      START INPUT

All of the I/O instructions default to select code 0 and must be configured 
to the actual TTY select code.

Yes.

Hence my confusion with your first sentence.
