I'm sort of a latecomer to all of this, but I've been reading through the posts trying to get an idea on how to get the best transfer rate possible when connecting to Q-Link.
Apparently, from what I've read so far, the maximum rate seems to be 2400bps, even using a SwiftLink patch. Some posts say that the 2400bps patch doesn't work for certain things like games, and it is another matter altogether when used in VICE.
If I understand correctly, the root of the issue is that the serial I/O code on the Q-Link disk still needs to be cracked. Once that is done, I assume it should be fairly simply to substitute some different code.
The last time I did coding for such things (back in '93), the Geoge Hug "Toward 2400" routines were the best thing available for obtaining 2400bps via the CIA chip. Is this still the case? The Hug routines were the basis for the stuff I wrote at the time.
For the SwiftLink, I had written my own custom code for Color 64 v8. It used a 4K input buffer to avoid losing data at the maximum transfer rate.
I'd be foolish to think I was the only one who had written such things... but I just wanted to offer up the source code if anyone was interested. Both the CIA routines and the SwiftLink routines underwent heavy testing on a lot of systems back in the day.
