For modem to modem communications, start and stop bits were used up through 2400 baud when one bit = one tone. The method of one bit = one tone was dropped for other forms of encoding when modems started supporting connection speeds in excess of 2400 baud.
I assume you mean 2400 bps modems, i.e., v.22bis? Admittedly, it's been a while since I used one, but my recollection is that 2400 bps modems operate at 600 baud, with 4 bits/baud using QAM.
This matches my recollection. I think it was 1200 bps that was the last 1 bit per baud modem. Cheers, -- jra -- Jay R.
