nqc -SCOM2
You need to be careful about upper/lower case for options. I know its
annoying, but there are a *lot* of options, so case is important. In
the case of specifying the serial port, the option is immediately
followed by the serial port name (no space). Kinda like the -I, -L, -D
and other options for gcc.
When in doubt, type
nqc -help
which prints a summary of the options. For example:
nqc version 2.2 r2 (built Oct 22 2000, 14:25:55)
Copyright (C) 1998-2000 David Baum. All Rights Reserved.
Usage: nqc [options] [actions] [ - | filename ] [actions]
- : read from stdin instead of a source_file
Options:
-1: use NQC 1.x compatability mode
-T<target>: target can be RCX, CM, Scout, or RCX2
-d: download program
-n: prevent the system file (rcx.nqh) from being included
-D<sym>[=<value>] : define macro <sym>
-E[<filename>] : write compiler errors to <filename> (or stdout)
-I<path>: search <path> for include files
-L[<filename>] : generate code listing to <filename> (or stdout)
-O<outfile>: specify output file
-S<portname>: specify serial port
-U<sym>: undefine macro <sym>
Actions:
-run: run current program
-pgm <number>: select program number
-datalog | -datalog_full: upload datalog
-near : set IR to near mode
-far : set IR to far mode
-watch <time> | now : set RCX time
-firmware <filename> : download firmware
-firmfast <filename> : download firmware at quad speed
-sleep <timeout> : set RCX sleep timeout
-msg <number> : send IR message to RCX
-raw <data> : format data as a packet and send to RCX
-remote <value> <repeat> : send a remote command to the RCX
-clear : erase all programs and datalog in RCX
-api : dump the standard api file (e.g. rcx.nqh) to stdout
-help : display command line options

| (...) I tried what you said quite a bit but it just says "usage error: try nqc-help' to display options" My serial port works fine for my Scout Tool program. and I have tried to switch the RCX to the scout like this "nqc -T Scout" and "nqc -TScout" (...)
