/* RC 2000 BAUD RATE - ADDRESS SPECIFICATION **
The baud rate and address must be set before communication with a
host is possible. These quantities can be specified in the CONFIG
mode. The range of acceptable addresses is 49 to 111. The
possible baud rate values are 300, 600, 1200, 2400, 4800, or 9600.
The usual SA Bus baud rate is 9600. For completeness, the
transmission parameters are repeated here: 7 data bits, even
parity, 1 stop bit. */
/* RC 2000 ONLINE/OFFLINE **
To enable remote mode on the RC 2000, the internal
remote$mode$enable$flag must be set. This flag is set at the
'REMOTE MODE ENABLE' prompt in CONFIG mode. When this flag is
set, remote mode can be entered in two ways. One way remote mode
can be activated is by depressing the mode button. Remote mode
can be found just after AUTO mode. The second way remote mode can
be activated is when a valid command arrives via the serial port.
