8157Re: [NTO] Recover Serial Port
- Aug 23, 2008Hi
I do not think there is a exit as such you are relying on the program
letting go of the serial port when you exit the programA .
Would you have two serial ports one for A and the other for B ,another
thought is to find an I\O card and use another slot.
THANKYOU DAVE M
