HP 82160A HP-IL Module

HP 82160A While the HP 82160A HP-IL Module is plugged into the calculator, the following functions are available for your use. All functions are programmable except as noted below. Appropriate peripherals must be connected to the Hewlett-Packard Interface Loop for the functions to be executed normally.
Calculator flags indicated below determine how the interface module performs certain operations. When a flag is set, operations are performed as described.

Printer Operations

Functions marked with * are for the HP82162A Thermal Printer only.

ACA Accumulates the ALPHA register into the print buffer.
ACCHR Accumulates a character into the print buffer. Uses X-register.
ACCOL * Accumulates a specified column of dots into the print buffer. Uses X-register.
ACSPEC * Accumulates a special character into the print buffer. The character is defined by using BLDSPEC. Uses X-register.
ACX Accumulates the X-register contents into the print buffer.
ADV Advances the printer paper and prints the print buffer right-justified.
BLDSPEC Executed up to seven times, builds a special character using specified columns of dots. Accumulate using ACSPEC or store in a register. Uses X- and Y-registers.
FMT * Accumulates a format specifier into the print buffer. Leading or trailing specifier centers output; internal specifier prints left- and right-justified.
LIST Lists specified program lines. Not programmable.
PRA Prints the ALPHA register left-justified.
PRAXIS * Prints and labels a y-axis. Uses R00, R01, R02 (column width), R04.
PRBUF Prints the print buffer left-justified.
PRFLAGS Prints flag status and other calculator information.
PRKEYS Prints a list of currently reassigned keys.
PRPLOT Plots a function interactively. Prompts for parameters and stores data in R00 through R11.
PRPLOTP * Plots a function noninteractively. Uses R00 through R11: R00 (Y MIN), R01 (Y MAX), R03 (optional plot symbol), R04 (AXIS), R08 (X MIN), R09 (X MAX), R10 (X INC), R11 (NAME). R06 contains x value.
PRREG Prints the contents of all storage registers.
PRREGX Prints the contents of registers specified by X (bbb.eee).
PRΣ Prints the contents of the statistics registers.
PRSTK Prints the contents of the X-, Y-, Z-, and T-registers.
PRX Prints the contents of the X-register.
REGPLOT * Plots a single function value (from X-register). Uses R00, R01, R02 (nnn.aaa), R03.
SKPCHR * Accumulates skipped characters into the print buffer Uses X-register.
SKPCOL * Accumulates skipped dot columns into the print buffer. Uses X-register.
STKPLOT Plots a single function value using X (nnn.aaa), Y (Y MAX), Z (Y MIN), T (y value).

Printer Flags

Flag 12: Double Wide
Prints and accumulates characters double width.
Flag 13: Lowercase
Prints and accumulates characters in lowercase.
Flag 21: Printer Enable
Performs printer operations normally in programs. VIEW and AVIEW print and do not halt program execution. (Automatically set when flag 55 is set.)
Flag 55: Printer Existence
Indicates a printer is connected to the system. (Automatically set when printer is first detected.)
Flags 15 and 16: Print Mode (not used for HP 82162A Thermal Printer)
 
Flag 15 Flag 16 Print Mode
clear clear MAN (manual)
clear set NORM (normal)
set clear TRACE
set clear TRACE with stack option

Mass Storage Operations

CREATE Creates a new data file with specified number of registers and filled with zero values. Uses ALPHA and X-registers.
DIR Displays (and prints) a directory of stored files. Indicates file type: PR (program), DA (data), KE (key assignment), ST (status), and WA ("write-all"). Indicates file options: A (automatic), P (private), and S (secure).
NEWM Prepares a new medium for storing files. Prompts for number of files in directory space. Not programmable.
PURGE Removes a file from the medium. Uses ALPHA register.
READA Reads a "write-all" file and sets the calculator accordingly. Uses ALPHA register.
READK Reads a key-assignment file and reassigns keys accordingly. Uses ALPHA register.
READP Copies a program file into program memory, replacing the last program in memory. Executed in USER mode, program key assignments become active also. Uses ALPHA register.
READR Copies a data file into the calculator's registers until all file registers copied or all storage registers filled. Uses ALPHA register.
READRX Copies part of a data file into registers specified by X (bbb.eee). Starts at current register in data file.
READS Reads a status file and sets the calculator status. Pending program returns are lost. Uses ALPHA register.
READSUB Copies a program file into program memory, placing it after the last program in memory. Executed in USER mode, program key assignments become active also. Uses ALPHA register.
RENAME PRenames a stored file. Uses ALPHA register.
SEC Makes a stored file secured against being erased, renamed, or altered. Uses ALPHA register.
SEEKR Positions the medium to a specified data file and register. Uses ALPHA and X-registers.
UNSEC Makes a stored file not secured. Uses ALPHA register.
VERIFY Verifies that a stored file can be read. Uses ALPHA register.
WRTA Stores a "write-all" file onto the medium. Uses ALPHA register.
WRTX Stores key assignments of system functions onto the medium. Uses ALPHA register.
WRTP Stores a program and its key assignments onto the medium. Uses ALPHA register.
WRTPV Stores a program and its key assignments onto medium and makes the file private. Uses ALPHA register.
WRTR Copies all storage resisters into a data file. Uses ALPHA register.
WRTRX Copies some storage registers into a data file as specified by X (bbb.eee). Starts at current register in data file.
WRTS Stores calculator status onto the medium. Uses ALPHA register.
ZERO Fills a data file with zero values. Uses ALPHA register.

Mass Storage Flags

Flag 11: Automatic Program Execution
Used with WRTP, WRTPV or WRTA, sets a program for automatic execution when copied back into the calculator from the keyboard. (For WRTA, execution set to start at current position in program memory.)

Interface Control Operations

AUTOIO Sets the interface to Auto mode.
FINDID Finds the address of a specified device type and places the address in X. If the device is not found, zero is returned. Uses ALPHA register.
INA Inputs an ALPHA string of up to 24 characters from primary device.
IND Inputs a decimal number from primary device.
INSTAT Inputs status information from pri- mary device, sets or clears flags 00 through 07 accordingly, and places decimal status number in X.
LISTEN Sets a device as a listener, or removes all listeners for X = 31. Uses X-register.
LOCAL Sets primary device to its local operating mode.
MANIO Sets the interface to Manual mode.
OUTA Outputs an ALPHA string to primary device. Uses ALPHA register.
PWRDN Sets all devices to their low power state.
PWRUP Sets all devices to their operating power state.
REMOTE Sets primary device to its remote operating mode.
SELECT Selects a device as the primary device. Uses X-register.
STOPIO Stops I/O communication in the loop.
TRIGGER Triggers all devices set to respond (listeners).

Interface Control Flags

Flags 00 through 07: Device Status
  When set by INSTAT, indicate that corresponding status bits of a device are 1's.
Flag 17: Suppress End-of-Line
End-of-line indicator is not used. OUTA does not send CR and LF. INA ignores CR and LF.
Flag 32 Manual Mode
Indicates interface is in Manual mode.
