I have been trying to read "Character Input" from a serial port from
C on a SUN Sparc (SUN OS 4.1.3), and have gone thru infinite variations
of READ, FGETC, ACONONICAL, NON-CONONICAL, STREAMS, IOCTL's til I cant
see anymore but can only read when a CR is sent (Line Mode).

Any help would be greatly appreciated. Follows my latest attempt:
(JEFF.H) is standard set of includes...

#include "jeff.h"

main(argc, argv)
     int argc;
     char* argv[];
{

FILE *in;
int out;
int i,c;
char filen[80];
char device[80];
char line[100];
char ch;

/*
strcpy(device,argv[1]);
*/
strcpy(device,"/dev/cuAe");


out=open(device,O_RDWR);
if(out==NULL) {
        printf("CANNOT OPEN %s\n",device);
        exit(0);
        } 
        else
        printf("%s OPEN\n",device);

strcpy(line,"Test Test");
write(out,line,strlen(line));
printf("Test Line Sent!\n");



while(1) {
        memset(line,0,sizeof(line));
        c=read(out,line,1);
        if(c>0) {
                printf("%s",line);
                if(line[0]==113) break;
                }
        if(c<0) {
                printf("Read Failure errno=%d\n",errno);
                perror("");
                }
        }

printf("\nDone.\n");
exit(0);
}
