that 1 or more bits of the received character were corrupted
in such a way as to change the character's parity.
EORN 2
The GPIB-MAC records this error when characters arrive at
the serial port faster than the serial port can accept them
When this error occurs, one or more characters sent to the
serial port have been lost. If this error occurs, check to see
that the GPIB-MAC and your Macintosh are using the same
serial port settings.
The GPIB-MAC records this error when the GPIB-MAC's
internal serial port buffer overflows. This should only occur
if XON/XOPP is disabled.
The GPIB-MAC records this error when a character is
received whose stop bits are not in the expected place. This
can happen when the number-of-bits-per-character setting of
the GPIB-MAC does not match your Macintosh. It can also
happen if the baud rates of the GPIB-MAC and your
Macintosh do not match, or if one side of the serial link does
not use parity and the other side does.
