It is to support a myriad of devices that use ttl levels such as band
decoders that drive antenna switches, bandpass filters, etc.

Subject: [Elecraft] [K3] Pull-up Question
I've a question on the pull-up resistor mod for the KIO3 board: is this
addition being done to support "legacy devices" or is it the
wave-of-the-future (or none of the above)? If current interface "standards"
don't require the pull-up capability and the outlook for the future is the
same, I think I will take a pass on doing the mod. Otherwise I shall take
the K3 apart again and add the resistors (I skipped that mod when doing the
K3 upgrades but have decided it might be best to be sure).
