We have been using an HP92916A bar code reader as part of a test
system programmed in BASIC/UX. Under BASIC, the bar code reader
behaved the same as if the input came from the keyboard.
We are now using a software platform written in C under HP-UX, and we
want to talk to the bar code reader. I have been able to read data
when the reader is set up for ASCII transmission, but for
compatibility with the BASIC software, I need to leave it set up for
USASCII keyboard mode.
The man page hil(7) says:
"Hil can only read HP-HIL keyboards in raw keycode mode. Raw keycode
mode means that all keyboard input is read unfiltered. HP-HIL
keyboards return keycodes that represent key press and key release
events".
The data I get agrees with this - it is not ASCII. I have two
questions:
1. Are the raw keycodes documented somewhere, so that I can convert
them to ASCII? If so , where?
2. Am I going about this the wrong way?
The following is some of the code I am using to read the bar code reader.
This works when the reader was in ASCII mode.
I am running HP-UX 7.0 on a model 360.
The device file for the bar code reader looks like:
crw-rw-rw- 2 root other 24 0x000030 Aug 14 1990 /dev/bar_code
#include <stdio.h>
#include <fcntl.h>
#include <sys/hilioctl.h>
void get_bar_code(code)
char *code;
{
int fd;
unsigned char packet_length;
unsigned char time_stamp[4];
unsigned char poll_record_header;
unsigned char data[20];
/* open device file */
fd = open("/dev/bar_code",O_RDONLY);
do {
read(fd, &packet_length, sizeof(packet_length));
read(fd, time_stamp, sizeof(time_stamp));
read(fd, &poll_record_header, sizeof(poll_record_header));
read(fd, code, packet_length-6);
code += packet_length-6;
}
/* carriage return indicates end of bar code */
while (*(code-1) != '\r');
/* terminate string in null (and remove \r) */
*(code-1) = 0;
/* close device file */
close(fd);
}

I developed this table as part of a keyboard investigation. It should contain what you need.
