>Environment:
FreeBSD steveg1.comtrol.com 3.0-971006-SNAP .....
>Description:
Our RocketPort driver currently supports only 32 ports.
>How-To-Repeat:
Try to use more than 32 ports
>Fix:
Change MAKEDEV to use higher minor numbers.
changed rp.c to use the new minor numbers.
Difference of rp.c from 3.0 current dated 2/19/98 (55391 bytes)
