Attempting to setup an Apple II BBS

[Dr. Felch]

I mean, I think it is? As mentioned I got it working properly for a very very brief moment so i'm sure the SSC itself is fine, and unfortunately I don't have the funds to grab another one at the moment, especially if i'm not positive that's the reason. GBBS doesn't load if I use &C1, and &C0 only works if I include &S0. I see someone else on here is having the same problem I am with GGBS Pro except they're using a IIgs, including the system, time and icon in the corner freezing when a connection is made and getting it to work 1 time and then never again after that.

EDIT: ok at 9600 baud with &C1&S0 in the init string gbbs loads but doesn't acknowledge the connection to the wimodem, whereas with &C0&S0 gbbs freezes when the connection is made.

Like I said, &S0 does absolutely nothing. In my code it simply returns and ignores the command (OK is returned if this command is sent by itself). The command is supported only to prevent an error from being generated should something use it. I think I had to add this for some BBS program to not return an error (maybe GGBS?)

&C1 means that the DCD line will follow the connection state. So, when there is no connection that line is HIGH and when there is a connection that line is LOW. If the BBS looks for the DCD line to know if it is connected then this command would to be enabled. &C0 always sets the DCD line low (like it is always connected).

There is a polarity inversion command you could try, but I doubt anything would ever use that since the Hayes standard is the default polarity.

[Dr. Felch]

Is there a program available for the apple II that I can use to test my SSC to see if it's fully working?

[admin]

I am not sure. You could do a simple test to see if the registers were working but you would need some sort of loop-back test harness to know the RS232 side is actually working or not.
