does anyone actually *know* that the difference between the 16450 and 16550 PCMCIA modems is real? Of course I understand the effect of the difference in the case of a normal serial port, but here we are talking about a simulation, and it is not technically obvious to me at all that the fact that the external simulated interface is 16450 will make it impossible to do "_ANY_" multitasking at all. comments?
