501; Reader/Writer Routines
502;
503; For serial drives, we pack the port number and baud rate into a single byte, and thus
504; we need to take care to properly read/write just the bits we need. In addition, since
505; we use the Port/PortCtrl bytes in a special way for serial drives, we need to properly
506; default the values stored in both these words when switching in and out of the Serial
507; device choice.
508;
509; Writers:
510; Parameters:
511; AX: Value that the MENUITEM system was interacting with
512; ES:DI: ROMVARS location where the value is to be stored
513; DS:SI: MENUITEM pointer
514; Returns:
515; AX: Value to actually write to ROMVARS
516; Corrupts registers:
517; AX
518;
519; Readers:
520; Parameters:
521; AX: Value read from the ROMVARS location
522; ES:DI: ROMVARS location where the value was just read from
523; DS:SI: MENUITEM pointer
524; Returns:
525; AX: Value that the MENUITEM system will interact with and display
526; Corrupts registers:
527; AX
528;

530;
531; No change to Device byte, but use this opportunity to change defaults stored in wPort and wPortCtrl if we are
532; changing in/out of a Serial device (since we use these bytes in radically different ways).
