Status represents a combination of GP485 conditions. Inside the GP485,
status is stored as a 16-bit integer. Each bit in the integer represents a single
condition. A bit value of 1 indicates the corresponding condition is in effect.
A bit value of 0 indicates the condition is not in effect. Because more than one
GP485 condition can exist at one time, more than one bit can be set in status.
The highest order bit of status, also called the sign bit, is set when the GP485
detects either a GPIB error or a serial port error. when status is negative, an
error condition exists.
