Why did recent RealPort upgrade change our tty reference from ttynn01 to tty__dgrp__nn01?

Recently upgraded from RealPort 1.9-30 to 1.9-34 on Redhat EL 6. Now our /dev references are tty_dgrp_aa_01 when they used to be ttyaa01. ttyaa01 now has a symbolic link to tty_dgrp_aa_01. We want the old dev references back. Thanks.

In newer kernels, UDEV is responsible for device creation. The symbolic link of /dev/ttyaa01 will work the same as with previous kernel/driver versions.
