It's a little bit ON-topic because I would never have discovered this if I
wasn't playing with my C64's modem.
Btw, for 6551 ACIA hackers, I seem to be having some trouble detecting
carrier with my SwiftLink. I know that in the cartridge it is always tied on
with pull-ups so that the 6551's receiver stays on, and so Dr Evil Labs/CMD
directed DCD to come over DSR instead (this is internal to the cartridge).
But all I get is the DCD "phantom" always-on bit when I check the register,
even if I get a successful connect -- I never see the DCR line come up. Are
there DB-25 to DE-9 cables that just don't connect DCD?
While I was testing this out, I dialed the local AOL access number just to
get something with a carrier so that I could watch the 6551 status register
when it connected. Besides the DCD/DSR chachacha above, I got an interesting
prompt (X'ed out the naughty bits)
Level 3 Comm nasXX.XXXX UQKT2
Username:/login:/Login:
Not your typical POP. I know who Level 3 is, and I do have an AOL login. It's
interesting, however -- I was just expecting 8-bit "garbage" and not an actual
prompt. I disconnected immediately since I wasn't interested in raising
anyone's blood pressure at Level 3's security centre. What kind of protocol
might this use (besides AOL's internal one, of course)?
