Help wanted to communicate with Virtual XP via a serial por

[ukdodger]

Hi, I'm running a Windows 7 home host with virtual XP on Oracle virtualbox using a Samsung RV510 Laptop.

I have to upload data from a Sharp ZQ-570 Organiser into the XP. The software on the XP works but needs a comms port. I have two problems.

1, How to configure Virtualbox to a comms port.

and

2, The Organiser has a 9 way female connector to connect to my Laptop. The Laptop only has USB ports. There appears to be a lot of 9 way to USB cables around but which one do I need. It seems they all need a driver and I have no idea which one.

Any help greatly appreciated.

I'm fairly certain this is not a VirtualBox question but you never know. Someone may own the same organizer.

Thanks that's what I'm hoping.

I would imagine the 9way female connector is nothing more than an RS232 serial port in DCE rather than DTE configuration and probably originally came with a cable to connect it to a serial port on a PC.

USB-RS232 adapters generally come with either FTDI or Prolific silicon and once you have one you will just be able to download the drivers from the appropriate website should the Windows 7 host not automatically find them from the Windows update site.

In your Windows XP VM enable serial port 1 and configure it as IRQ4, I/O Port 0x3F8 and set the mode to "Host Device". In the "Path/Address" field add the COMx entry the Windows 7 host assigns to the USB adapter (mine uses COM3).

Attach the Sharp Organizer to the USB-RS232 adapter and it should appear to Windows XP as COM1.

Cheers Andy. That's a great help. I'll give it a bash.
