Check the permissions on /dev/ttyS1. I think the default is for it to be locked down to superuser only. If this is the case, then running nqc from a normal user account would cause the error you got. You'll need read/write rights to /dev/ttyS1 in (...) (25 years ago, 29-Dec-99, to lugnet.robotics.rcx.nqc)
