Assuming you have one card not two connected, it looks like you should set the device as 4 ports not 8. > > Now some questions: > > I first listed all 8 ports with PUC_COM_POW2(3) because I think I saw a > similar device (a Boca card or something) using it. it worked fine (one of > the ports was connected to a different machine an cu could pass text).

Sets the clock multiplier - even if this is set wrongly a null-modem between ports on the card will still work so be sure to test all the ports to a different machine and make sure the speeds are right; sometimes not all ports have the same multiplier. > Why do the first four ports probe to 16 bytes but not the next four? unsure. > What is up with the “couldn’t get subregion” message?

Presumably because it's 2x 4-port so the 'extra' 4 ports aren't really there. > This is my first real attempt at development of this type so I am pretty happy > about this. I would love for 5.9 to have support for this card. It probably only needs a few tweaks so there might well be time for this.
