I tried Reflex 62/64 driver for SCR 60 with some changes on
communication protocol, but reader gave no response. If I put some lines
in IO_Write() serial.c, the driver works.
// New lines added
FD_ZERO(&rfds);
FD_SET(handle, &rfds);
rval = select (FD_SETSIZE, &rfds, NULL, NULL,
&tv);
// New lines end here
tcflush(handle, TCIFLUSH);
if (write(handle, &c, 1) == 1) {
printf("Data write: %c\n",c);
return TRUE;
}
The difference between two readers is: for commands Reflex sends one
byte and then will read one byte. But for SCR 60 it sends several bytes
as a command, and then read bytes. Is this the reason that causes the
above change?
Thanks
Jenny
