Now you have us curious.  So, what was on the extra track?

I’ve actually had a 300 baud modem connect to an audio track on a CD. A long time ago when I was working at Napa Valley College, a student brought in a CD (I have no idea what band or album) that had an extra track which was a 300 baud modem recorded on it and he wanted to know what it was. To connect it to the modem I just played the track loudly and held up the handset on a phone near the speaker. It worked because at 300 baud there’s no two-way negotiation between the modems at all.  

One of these days I’ll get around to trying the same thing but uploading it as a YouTube video to see if someone else can make it connect to their modem.
