[BRLTTY] Trouble with Seika display and brlapi

[Rob Meredith]

Hi Samuel:

The simple program below does work with other displays. I tried it with another serial display. I have also confirmed that when lines are not appearing on the display, that the TSI display driver is not getting the dot patterns to send, so it appears not to be a communications issue between the the PC and the display.

  #include <stdio.h>
  #include <stdlib.h>
#include <brlapi.h>

int main(void) {
        int fd;
        fd = brlapi_openConnection(NULL, NULL);
        if (fd < 0) {
                printf ("Unable to open.\n");
                return 1;
        }

        if (brlapi_enterTtyMode(-1,NULL)>=0) {
                printf ("Got the tty\n");
                for (int x = 1; x <= 12; ++x) {
                        char line[256];
                        sprintf(line, "Line %i.", x);
                        brlapi_writeText(0, line);
                        getchar();
                } //for x
        }

        brlapi_closeConnection();
        return 0;
}

Does the same program work with another kind of terminal?  Could you
show us the code you are using to write strings?
