Has anyone successfully established a PPP link at 115200 baud from the LAN port on the TT (/dev/ttyS4) to a PC. I'd like to do 230400 baud if the TT can do it. I've done it with the modem1 and modem2 ports with no problems. And I'm fairly sure the cable is correct, unless someone can point me at a definitive cable. Thanks. Alan.
