Re: TypeMatic Rate

You'll need to read the value from the ESCD table stored in NVRAM.

Here is a start for you:

offset 13h holds a single byte that represents the typematic data

76543210
^^^
---- typematic rate (bits 4 thru 2
^^
------- typematic rate delay (bits 6 and 5)
^
--------- typematic rate flag (bit 7, enabled or disabled)

I am sure you can find lots more by searching the web, perhaps even
some sampe code although reading this location under DOS is trivial.

HTH,
