454; For serial drives, we pack the port number and baud rate into a single byte, and thus
455; we need to take care to properly read/write just the bits we need. In addition, since
456; we use the Port/PortCtrl bytes in a special way for serial drives, we need to properly
457; default the values stored in both these words when switching in and out of the Serial
458; device choice.
459;
460; Writers:
461; Parameters:
462; AX: Value that the MENUITEM system was interacting with
463; ES:DI: ROMVARS location where the value is to be stored
464; DS:SI: MENUITEM pointer
465; Returns:
466; AX: Value to actually write to ROMVARS
467; Corrupts registers:
468; AX

470; Readers:
471; Parameters:
472; AX: Value read from the ROMVARS location
473; ES:DI: ROMVARS location where the value was just read from
474; DS:SI: MENUITEM pointer
