(...) Currently there isn't any notion of an "error code" from the serial port class - opening the serial port just returns true/fals. I'm wary of adding error codes here because they'd need to be added in a portable manner (and across the Unix, (...) (25 years ago, 30-Dec-99, to lugnet.robotics.rcx.nqc)

Hi. I just got through fixing a similar problem with my linux box (the fix involved a lot of tedious changing IRQ's in the BIOS, with a lot of tedious rebooting in between). Beyond Dave's good advice, you might want to check out the linux serial (...) (25 years ago, 30-Dec-99, to lugnet.robotics.rcx.nqc)

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)

(...) I'm glad you're enjoying the book. Not including more information about where to put include files was definitely an oversight - I'll update the book's web pages when I get a chance. Dave (25 years ago, 22-Dec-99, to lugnet.robotics.rcx.nqc)

I was using the RcxCC program. I put the nqh file in the RcxCC directory and everything worked fine. Thanks for the information. By the way, I am really enjoying your book. I hope everyone gets a chance to read and use it. -- Bob Fay (...) (25 years ago, 22-Dec-99, to lugnet.robotics.rcx.nqc)

I am working my way through Dave Baums' Mindstorm book and I have lost my way regarding the #include command. The roboarm1.nqc program calls for roboarm.nqh to be included. The program will not compile because it "cannot open roboarm.nqh". Some (...) (25 years ago, 22-Dec-99, to lugnet.robotics.rcx.nqc)

(...) There is very little difference in the compiler itself between 1.0 mode and normal mode. Most of the changes are due to a new API file that is included (rcx_nqh.h).
