The sim-link may not fix old software. The problem has been software that just does an open("/dev/cua0", O_RDWR), this has to be changed to open("/dev/xxx", O_RDWR|O_NDELAY) with a subsequent fcntl() to reset this flag-bit. Otherwise, if carrier is not detected, the open() will wait until it is. Since the code has to be modified, might just as well change the device to the right one.
I recommend just `rm /dev/cua?` and see what breaks. You get to fix things only once.
