- * Terminate_Serial.c
- *
- * This is an example of using a termination array for reads from the serial
- * device. A termination array is set up for the characters Q, E, etx (CTRL-D)
- * and eot (CTRL-C). The EOFMODE flag is set in io_SerFlags to indicate that
- * we want to use a termination array by sending the SDCMD_SETPARAMS command to
- * the device. Then, a CMD_READ command is sent to the device with
- * io_Length set to 25.
- *
- * The read will terminate whenever one of the four characters in the termination
- * array is received or when 25 characters have been received.
- *
- * Compile with SAS C 5.10 lc -b1 -cfistq -v -y -L
- *
- * Run from CLI only
