NOTES
1. bname is the symbolic name of the new board, e.g., ibbna
gpib1 .
2. Values enclosed in square brackets ( [] ) are optional. The
default value is 0 for ibwait and 1 for all other functions.
3. v is a hex, octal, or decimal integer. Hex numbers must be
preceded by zero and x (e.g., 0xD ). Octal numbers must be
preceded by zero only (e.g., 015 ). Other numbers are assumed
to be decimal.
4. string consists of a list of ASCII characters, octal or hex
bytes, or special symbols. The entire sequence of characters
must be enclosed in quotes. An octal byte consists of a
backslash character followed by the octal value. For example,
octal 40 would be represented by
\40 . A hex byte consists of a
backslash character and a character x followed by the hex
value. For example, hex 40 would be represented by \x40 .
The two special symbols are \r for a carriage return character
and \n for a linefeed character. These symbols provide a more
convenient method for inserting the carriage return and linefeed
