497; Reader/Writer Routines
498;
499; For serial drives, we pack the port number and baud rate into a single byte, and thus
500; we need to take care to properly read/write just the bits we need. In addition, since
501; we use the Port/PortCtrl bytes in a special way for serial drives, we need to properly
502; default the values stored in both these words when switching in and out of the Serial
503; device choice.
504;
505; Writers:
506; Parameters:
507; AX: Value that the MENUITEM system was interacting with
508; ES:DI: ROMVARS location where the value is to be stored
509; DS:SI: MENUITEM pointer
510; Returns:
511; AX: Value to actually write to ROMVARS
512; Corrupts registers:
513; AX
514;
515; Readers:
516; Parameters:
517; AX: Value read from the ROMVARS location
518; ES:DI: ROMVARS location where the value was just read from
519; DS:SI: MENUITEM pointer
520; Returns:
521; AX: Value that the MENUITEM system will interact with and display
522; Corrupts registers:
523; AX
524;
525
526;
527; No change to Device byte, but use this opportunity to change defaults stored in wPort and wPortCtrl if we are
528; changing in/out of a Serial device (since we use these bytes in radically different ways).
