The serial ports on the HyperCom 3+ and HyperCom 4+ Zorro-Bus boards by
VMC are officially supported now. 
The drivers have been in NetBSD-current for a while, and have been tested
now and found to be working.
Support for these boards is included in the upcoming NetBSD-1.4 release, 
which is in its public test phase now.
