FreeBSD 7.4 & VSCom Serial Card Problem

S

sgn

I'm having trouble getting this working after upgrading to FreeBSD 7.x. I have this working perfectly in FreeBSD 6.x with sio, puc and com_multiport compiled into my kernel. It then shows up as cuad4 and cuad5 under /dev. In FreeBSD 7.x i only have cuad0 and cuad1 which is the Soekris Serial ports.

My system is a NET4501 with a VSCom PCI serial card (2 ports) and I'm using NanoBSD to build my CF image.

I appreciate any feedback you can give on how to get this working.
 
Hopefully someone has any inputs on this?

I gave a go at version 8.2. Seems the puc driver connects to the serial ports there as well. I would prefer to get this working with 7.4, but all my efforts have came up short. Would really appreciate some pointers.:stud
