It's like saying, I heard you could apply your breaks with a special hydraulic cable. True but what info does that give you.
Many modern scanners allow for programming by computer and partial or real time total control with a virtual scanner displayed on the screen. Do some research for a while and see what all is out there.
you said you have a pro95. You can buy a cable that will let you program your scanner from your computer using a free software program called WIN95 from www.starrsoft.com. The cable is radio shack model 20-289 and you can't believe how easy it is to program your scanner with the software. The same cable works on the digital Pro96, 2096 and other radio shack models.
