Use it with the VIC?: Enhanced Commodore 64 RS232 Serial Adapter v2

[pixel]

Time to finally plug something into the user port. But does this thing have any value in the 9600 baud range for the VIC? Should one buy it at all, or are there any issues that'd bite one in the backplate?

Thanks a million in advance.

Back in the "long, long ago time," my VIC would occasionally drop data at 2400 baud just relying on the onboard 6522s (my SupraModem from then still works fine), and only 1200 baud was reliable. 9600 would be a big step up, indeed. At US$30, it might be worth a gamble.

"UP9600" is a c64 specific hack, it uses the serial shift registers of the CIA

everything else should work fine with the VIC20 though

Thank you very much! I'll grab one then.

I've documented the known problems with the KERNAL RS-232 routines here. In summary, bidirectional data is reliable up to 1200 baud, you can have 2400 baud, but only in one direction. Hardware flow control is plain broken, you need something implemented in software to avoid buffer overruns.

Thanks! … and oops. Should be fun to play with any way.
