I do this all the time (have one program hold the serial device
open whilst I execute another). Are you sure you are using the
1.3 serial.device ???
There is a problem... many terminal programs and other programs
do not open the serial.device SERF_SHARED !! THIS IS WRONG! You
programmers out there, ALWAYS OPEN SERIAL.DEVICE SERF_SHARED !!
The other problem is that the serial.device will refuse to
do a SDCMD_SETPARAMS call while active requests are pending, so
if you do use something similar to what I've described above you
have to be sure that the first program doesn't have any active
requests when it executes the second program.
