Using Fs/2 Or Fs3 Software - Husky MP2500 Manual

18.2 Using FS/2 or FS3 software

A program that was especially written for the H FS/2 or FS3 should run
USKY
with little or no changes on the MP2500, unless it relies on any of the
facilities which have been deleted within the MP2500, or relies on software
timing loops (the MP2500 is considerably slower than the FS3, but about
the same speed as the FS/2).
Note that the MP2500 has a single communications port - serial port, COM2
only.
If the program calls a function which is not provided by the MP2500 BIOS,
the call will return with the carry flag set to indicate failure.
For a more detailed description of the differences between the FS/2, FS3
and the MP2500 from a programmer's point of view, see Appendix G.
