An automatic modulation mode selecting unit (208) and a method (100) provide for selection from a plurality of modulation modes having an optimized transmission time for a data file. This is particularly useful where a small data file is to be transmitted, such as for a hand-held message pad. The present invention may select a modulation mode having a slow data rate but a short training time to achieve a shorter transmission time a small data file in comparison with using another modulation mode having a fast data rate but a longer training time, and thus a longer transmission time. The automatic modulation mode selecting unit includes a mode select controller (202), a mode computer (204), and a mode-select switch (206) for selecting a modulation mode based on a calculated optimized transmission time.

An apparatus (200) and method for load balancing for a processor (103) operable in data terminal equipment (102), such as a personal computer or workstation, for operation of a data communications program for data transmission and reception over a communications channel (105), concurrently with the operation of other applications programs. The apparatus includes a loading selector (205) coupleable to a user interface (100) for selection of a data transfer priority. A priority translator (210) coupled to the load selector (205) maps or translates the data transfer priority to a modulation mode or to a subset of modulation modes. The priority translator (210) may also determine processor availability, which is then also mapped to a modulation mode or to a subset of modulation modes. A modulation mode controller (215) coupled to the priority translator (210) then limits or overrides automode functions or operations during a training period of the data communications devices for data transfer, limiting the modulation mode to one within the subset of modulation modes. Depending upon the data transfer priority selected by the user, the processor (103) has sufficient remaining availability for the concurrent and effective operation of other applications programs.
