[Trlog] TR-Log USB question

[Igor Sokolov]

TR4W supports networking. I know that quite a few operators use 2 networked 
computers for single op 2 radio and hardware lockout on PTT. There are 
several advantages in that approach. Most notably is the fact that one is 
left with 2 copies of the log. Even in case of failure of one of the 
computers you are still able to continue to operate. Another advantage is 
that with 2 screens you can have 2 different band maps simultaneously.
