None of the developers have felt the need (so far) to have

in that mode all the time for reliability reasons. Many people used
to replace the factory EPROM with a special KISS EPROM that would do
nothing else.
The nice thing about those EPROMS is that they don't mysteriously
drop out of KISS mode unexpectedly.
Unfortunately KISS EPROM images are only available for TAPR TNC2s and
their many clones (MFJ, DRSI. Paccomm, Symek). These aren't easy to
find anymore because some of the chips used have long been
discontinued, however the Tiny-2 is still on Paccomm's web site. MFJ
1270s often show up at hamfests and swap meets. There are even a few
TNCs on ebay right now.

I run KISS only EPROM's in 4 MFJ1270B's on my Linux system. I found the
KISS only EPROM offered two advantages over a Native Mode EPROM that
contained KISS.
1. The TNC never comes out of KISS mode unexpectedly.
2. The KISS only EPROM solved many strange timing problems that the
Native Mode EPROM exhibited when in KISS mode. Things like transmitting
over incoming data, not transmitting data that the computer sent to the
TNC, etc, all went away when the KISS only EPROM was used.
