PowerBook J8 Modem Port Pinout?

[Ron's Computer Videos]

Has the pinout of the J8 modem port for PowerBook 1XX models been documented by the community?

If so, would you please share it here?

Thank you!

Ron

While I'm not sure if the community has documented anything, the official Apple Developer Note has information on the modem interface. https://www.powerbook.micahgartman.com/dev/dn_140_170.pdf
It provides some pretty handy information on pinouts, timings, and other specifications required for developing a compatible modem.
(modem information starts on page 37/pdf page 46)
