Been there, done that (I wrote my own driver for the bisync card, so I didn’t have the latter problem, just had to tame a barely documented Motorola chip “helping” with the already weird DLE handling). I’d still prefer doing that again over today’s spam problem.
(There actually is a teachable lesson here, which is about getting rid of gateways. But that’s for another day…)
