Does the on-board modem support 2400 bps?
In what Convergent considered future releases of the UNIX PC (P6), there was to be a 2400 bps modem. This machine was never fully developed to production levels, and therefore there is no 2400 bps modem. As the existing OBM is a proprietary AT&T chip, the likelihood of there being a drop-in upgrade is remote at best. Interesting trivia: The P6 machine was to have a color video, 60MB QIC tape, as well as a 68020 CPU paired with a 68881 FPU.
