Solving number sequence

Curiously, the numbers seem to be made up of two or three 2-digit numbers. These 2-digit numbers range from 49 to 57. That happens to be the range of the decimal representations of the ASCII codes for the digits 0-9.

Converting the 2-digit decimal numbers to their 1-digit ASCII characters yields:

68, 64, 55, 124, 95, 124, 119, 51, 46, 108, ?

I don't see a pattern in this. However, if ASCII codes were used once, perhaps they were used twice.

Converting these decimal numbers to their ASCII characters yields:

D, @, 7, |, _, |, w, 3, ., l, ?

That next-to-last character is a lower case L.

Does that mean anything to you?

Doesn't look like much in "1337"...we get Da Tu We.l ?

If we convert to hex we get

44 40 37 7C 5F 7C 77 33 2E 6C

I think you're right about it being something to do with key codes

Thanks guys, this one was unfamiliar to me, so I tried different ways.
