@drwho @sabi depends on the #POTS / #PSTN system.
In some cases, that may be it...
- But I usually don't consider vandalism as a valid strategy when cyber-nomading...
The 2.400bps limit is what can be achieved with a Konnex Konnector Acoustic Coupler on the carbon/graphite mic & speakers of #US payphones...
In #Germany, your limit was 56kBit/s or 64kBit/s because #HyTNAS means you always get a V.92-capable line that gets switched to (also permanently present, but potentially disabled) #ISDN channel if you can just replace the handset, but with the absurd decision by @BNetzA to allow #DTAG to shutdown the #HyTNAS in favour of shitty #Vectoring-#DSL / #VDSL you can't get shit to work at all...
@kkarhan @drwho @sabi @BNetzA 2400 was the first "big step", below that just too easy to out-type or out-read. It's also the fastest I could get working over satellite phone relay from the arctic (2-4s latency), quite robust to bad lines or the like.
Past that, everything of course became a bit quicker, but from 1200 -> 2400 on the BBS's for me felt like dial-up -> DSL.
