The second group of commands is included to aid developers
of third party software. The characters "1,2,3" will not be inter-
cepted or interrupted by off-the-shelf serial port software pack-
ages, whereas the control characters very likely will be.
Do not attempt to communicate with the calibrator during its
power-up sequence. The response is undefined. All PC port
commands may be ignored after this attempt.
During normal operation, the above six characters are recog-
nized, all others are ignored.
During a self-test sequence, i.e., the TEST key was pressed, all
characters are ignored, including the six PC port commands.
The PC port operates at 4800 baud, no parity, 8 data bits and
1 stop bit.
The start of a record character is a tilde (0x7E ~ ~) (Hex Ascii
Key). The end of a record character is a line feed (0x0A LF
^J). A record is made up of four fields in the case of the Dose
Calibrators and five fields in the case of PET calibrators. The
field separator is one or more spaces (0x20 SP Spacebar).
The first field starts with the first character after the title and
continues until a space is encountered. It may be from two till
six characters in length. There are thirteen isotope names.
