UART on the VGA port? It's more likely than you think!

boot log

someone randomly found this TV on the street ¯\_(ツ)_/¯

@noiob sure, but this isn't I²C

@jn huh, reminds me that VGA got I²C

@lanodan for the EDID EEPROM, most importantly!

@jn haha https://wiki.nura.eco/wiki/KTC_msd6a358m2c1_(ktc-msd6a358m2c1)#Uart

@fun oh, they picked a different pair of pins, this one has RX/TX on 4/11, the old (unused) ID1/2 rather than the DDC pins

@jn Interesting!

@jn Yeah, and fun stuff like https://en.wikipedia.org/wiki/Display_Data_Channel which can allow to control monitor settings (depending on monitor capabilities).

@lanodan @jn oh yeah, GMBus console
