General Mach Discussion / Mach3 suddenly stopped talking to the serial port.Help please

« on: April 05, 2016, 04:05:27 PM »

Ancient Asus PC with LPT1 on the Mobo, been working fine for 2+ years, suddenly re-booted, and my Mach3 no longer works. There are no signals getting to my BoB, checked with a scope, but the port(0x378) tests ok with a test utility from http://lpt-port-test-utility.software.informer.com/download/. No signals can be seen on the  diiagnostic menu (Estop etc)

Can I re-install Mach3 without loosing my liicence?

I've got a new parallel/serial PCI board on order, but I cant quite decide if it's a software or hardware problem
