Toolbar for PCPro3

Aleph One Support

The Toolbar

The toolbar is used to change the way !PC’s emulation works.

• Freeze stops the emulation temporarily, and stops !PC hogging any (ARM) processor time.
• The Direct Serial and Direct Parallel options allow you to turn these parts of the emulation on and off while !PC is running, i.e. you can turn them off to allow RISC OS access to the relevant port. While turned off, PC applications will still think they have a valid serial or parallel port, but any data they send to the ports while these options are off is lost. So if you’re getting errors along the lines of Printer not responding or Modem not responding, check these settings and try again.

• The Turbodriver option mangles any data sent to the parallel port so that it will be successfully transmitted down a Turbodriver cable. So if you are switching between a printer attached by a Turbodriver cable and a Zip drive attached to the same parallel port on a normal cable, you may need to toggle this option, depending on which device is being used.
• Reset is equivalent to pressing the reset switch on a PC. Normally you only need to press the Ctrl+Alt+Delete key combination (the ‘three-fingered salute’ as it’s known colloquially). This has the advantage that if you are running Windows 95, and a task has hung, it will attempt to recover from the crash before resetting itself.
• Connect mouse switches !PC’s mouse emulation on; the RISC OS pointer will disappear at this point, and you will be able to move the mouse on the PC side instead. Click the middle button to get the mouse back to RISC OS again.
