[hcflinux] only root can access /dev/ttySHCF0 first time afterreboot

[Richard Leonard]

Thank you very much indeed, Jean-Simon. You were right of course. I don't seem to have /etc/rc.local, but adding the 3 modules loaded by  a manual 'modprobe hcfpciserial' to /etc/modules seems to have had the desired effect. 

I'm very grateful.

Regards
Richard
