TELEVAC
occupies the eighth bit of data, so that depending on the communications software used, the data length may have
to be changed to seven bits (as the parity bit is then added after the seventh bit).
The default data rate on a new unit is 9600 baud, but may be changed by way of the comm. interface to 300, 600,
2400, 4800, or 9600 baud.
A description of the various commands follows. They are separated into the different categories. First is presented
a Command Summary followed by a detailed description of the commands.
