Many simulators run instructions one or more orders of magnitude faster than the original systems did. Limiting simulated serial port input speeds to legacy bits per second values presents the arriving data much slower than the original systems ever saw it. Given the processing capacity of the simulated systems and the fact that the software and device interfaces only know how to deal with the legacy speed values there is a need to provide a way to allow input to arrive faster. This problem is solved by providing a speed factor as a part of a speed specification. For example a speed can be specified as "speed*factor" or "9600*10".
