Tinyrs is 38k4 serial port transfer program for the VIC-20 with a memory
footprint less than 256 bytes.
Tinyrs implements the simplewrite and simpleread protocols of over5.
It can be used with the over5 client program, or it can be used as a
VIC-20 to VIC-20 transfer.
Full source code + an NvRAM version for the Mega-Cart included.

The window client is on the over5 page: herenbla000 wrote:May you suggest me a windows client for tests and there is a cable schematic from/to PC ?

I've seen several schematics for a userport rs-232 converter. (only RxD and TxD are needed for the over5 protocol)
Can't remember where I saw one last. Does anyone have a link?
This is the original one by Commodore:

Then I need to buy a VIC1011-A interface using it with your Over5 program...
Since modern PCs uses the 9 pin serial port, I need also a 25 Pin to 9 Pin Serial Adapter for the VIC1011-A plus the cable to connect the PC and the Vic but do I need a null modem 9 pin cable or a normal 9 pin serial cable ?

No, a simple level converter does the job. Any mocrocontroller has same problem, it does need a level converter for communication with PC.

Thanks for the tip btw may be simple for you but not for me since I don't know German and I'm not familiar with low level hardware assembling.Diddl wrote:No, a simple level converter does the job.
It's much more easy for me to buy a VIC1011-A interface then build a "simple" level converter
PS: Someone has a Vic1011-A interface to sell ?

I think you would need a null modem cable.
Personally I have a Handic V24 interface together with a multihead (9 pin and 25 pin connectors in both ends) null modem cable.
Nicola, you could also use a Little USB for this.
You can connect little USB directly to your VIC and via USB to your PC. PC will supply a virtual COM port usable by any terminal program or any self written software.

Many thanks for all your suggestions, My problem is only in the vic side, I've a com port on my desktop but not on my vic
In the tlr's suggested post, i've found a nice item that is what I'm looking for if I don't find a Vic-1011A or similar.
Thanks again.

I believe Ruud picked up a couple of RS-232 interfaces at my place, although unknown exactly which Commodore computers they fit. I don't think I have anything available although I have a small stash of MAX232 chips so I could probably cobble something up if desired. I even have one or two userport connectors available.

Two, one with case, one without. I only found out later that it it was a RS-232 interface as well. FYI: it only contains a level converter. So the idea of using a MAX232 is good enough.carlsson wrote:I believe Ruud picked up a couple of RS-232 interfaces at my place

I don't know but I've this RS232 Serial Port To TTL Converter Module for DVD firmware modding, may I use it ?ruud wrote:So the idea of using a MAX232 is good enough.
