I'm having some troubles downloading to the RCX in Linux, I have
RXC_PORT set to /dev/ttyS1, which is the correct serial port, and then I
run nqc and get:
[brian@magic bin]$ ./nqc -d ../test.nqc
Downloading Program:error
Could not open serial port
[brian@magic bin]$
I don't know what the baudrate of the serial port is set to, nor do I
know what it should be set to, so that might be the problem.

| 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 (...)
