X OF QUERIES A query message unit is made up of a query header ending in an ASCII question mark character 3FH followed by optional whitespace and ended by a program message terminator To form a multiple query separate the individual program message units with a semicolon Examples ATTN ASSIGN b Multiple Query Commands ATTN ASSIGN 5 6 2 SYNTAX OF COMMANDS A command message unit is made up of a command header optionally followed by an argument and units and ended by a program message terminator If multiple commands are made on the same program line separate the individual command messages with a semicolon Arguments The 8311 supports a variety of argument types that can be used in program commands These types are e Character Program Data Integer Numeric Program Data Real Numeric Program Data Each data type has its own rules of syntax The following paragraphs provide the syntax rules for each of the argument types listed above Character Program Data This data type is comprised of the set of printable ASCII characters excluding those used as delimiters Character program data represents alpha or alphanumeric strings The use of alpha characters is case insensitive If the first character of the string is not an alpha character then the string must be delimited with either the ASCII single quote 7 or double quote character in order to distinguish the string from a numeric data type Examples

81. all characters received back to the terminal All data and commands are encoded using the ASCII character set The syntax for commands is the same as for GPIB operation and uses the syntax structure defined by IEEE 488 2 with the exception of the command termination rules Commands sent to the 8210A may be terminated with either an ASCII CR 0 00 or ASCII LF 0x0A character By default all responses from the 8210A are terminated in ASCII CR LF sequence 0 00 followed by 0x0A Software handshaking uses the XON XOFF scheme in which an ASCII DC3 0x13 character is transmitted by the receiver to indicate that data transmission should be halted XOFF and an ASCII DC1 0x11 character is transmitted to indicate that data transmission may continue XON Hardware handshaking utilizes the RTS and CTS lines When the RTS output signal is asserted true the unit is ready for data This signal should be connected to the external computer s CTS input signal so that when the receiver is ready the transmitter may send data When the unit is not ready for data it unasserts the RTS signal halting data transmission Likewise the unit monitors the CTS input signal during data transmission halting transmission if the external computer unasserts it s RTS signal In addition the 8311 unasserts the RTS signal while command execution is in progress For those systems incorporating local front panel controls the serial port can lockout local users pro
