 Name:         Bios console status

 Opcode:       1

 Syntax:       int16_t Bconstat ( int16_t dev );

 Description:  The BIOS routine Bconstat establishes the input status 
               of a standard peripheral device dev. The following 
               devices can be specified for dev:

                dev  Meaning 
                 0   prn: (Printer/Parallel port) 
                 1   aux: (Aux device, the RS-232 port) 
                 2   con: (Console) 
                 3   MIDI port 
                 4   Keyboard port 
                 5   Screen 
                 6   ST compatible RS-232 port (Modem 1) 
                 7   SCC channel B (Modem 2) 
                 8   TTMFP serial port (Modem 3) 
                 9   SCC channel A (Modem 4) 

               Note that the device numbers from 6 up are only 
               available from the TOS030 of the Atari-TT. A wrong 
               declaration for dev can lead to a system crash.

 Return value: The function returns -1 when there are characters 
               waiting in the buffer, and 0 if this is not the case.

 Availability: All TOS versions.
