The command probably worked. But the modem is probably configured
to return to preset config when it looses DTR from the computer. You
might need something like an &W at the end of the string to write
the setting to nvram. Your modems tech manual will have details
on this.

Tried anything like the following?
# cat /dev/cuaa1 &
# cat >/dev/cuaa1 < my_at_commands
Good Luck
