I was watching a video on this device and it was stated in the video that you could adapt this device to work on any computer with a serial port. I think it would be neat to get this working on the VIC-20, so I was wondering if anyone knew how hard it would be to adapt this to use the VIC's serial port.

Re: RetroNET for VIC-20
Depends on what the lowest baud rate it supports. The VIC can only do up to 2400 baud, and flow control is a problem. You'd have to use a software method like XON/XOFF as the KERNEL routines don't support symmetric RTS/CTS hardware flow control.

Ok, thanks! Hopefully this will work, it looks like a neat, low-cost solution to getting the VIC online.srowe wrote:Depends on what the lowest baud rate it supports.

Re: RetroNET for VIC-20
RetroNET is no fundamentally different from what can already be done with a WiModem (see here).
Except WiModem directly plugs into the userport, and RetroNET requires yet another set of level shifters to adapt the signals between TTL and RS232C. If you have a VIC-1011A and a RS232C 25pin-to-9pin-adapter/cable handy, you're already there, of course.
Those devices merely provide a bridge between RS232C and WLAN - they need the necessary infrastructure on the WLAN side and corresponding software on the VIC side to get anything useful done.

Ok, interesting. Thanks! Does the WiModem accept the Hayes command set? If not, what commands are used to interface with it?Mike wrote:RetroNET is no fundamentally different from what can already be done with a WiModem (see here).
