I've got a question about a very old (but reliable) piece of HP hardware -
the HP 150.  I'm aware that software on the HP 150 can sense the state of
the RS232 interface signals on the serial port, but I can't find any
documentation that describes how to read the interface (CD, RI, DSR, etc.).
For example, my old copy of REFLECTION 3+ knows how to read the signals and
indicate the signal state by displaying (or not displaying) and asterisk "*".
 
If anyone knows how read the HP 150 serial interface signals or has any
suggestions, I'd appreciate hearing from you.  Thanks!
