1. Its easy and free to use a virtual comm port signal 2. Most of the programs were from a time when using cat for turning radios on and off wasn't common so they are built with comm ports in mind 3. It has to be faster as its just raising voltage on a signal instead of queuing data thru a FIFO to a program to turn it on and off. Hence its more responsive to what your commands are.
I honestly can't think of a good reason to use cat when its this easy! 73 Neal Campbell Abroham Neal Software www.abrohamnealsoftware.com (540) 645 5394 NEW PHONE NUMBER Amateur Radio: K3NC Blog: http://www.abrohamnealsoftware.com/blog/ DXBase bug reports: email to [email protected] Abroham Neal forums: http:/www.abrohamnealsoftware.com/community/ On Thu, Jun 3, 2010 at 6:06 PM, Tim Ellison <[email protected]> wrote: > "I would also recommend avoiding using cat commands in MixW" > > Why?
