I did the same thing with crynwr's cygwin and legos some days ago and found
out that I have to set RCX_PORT to COM1 or so and not DEFAULTTTY or such
name by checking the source of firmdl.c:
...
#ifdef LINUX
#define DEFAULTTTY "/dev/ttyS0" /* Linux - COM1 */
#else
#define DEFAULTTTY "/dev/ttyd2" /* IRIX - second serial port */
#endif
...
/* Open the serial port */
if ((tty = getenv("RCX_PORT")) == NULL)
tty = DEFAULTTTY;
fd = rcx_init(tty);
...
even if the doc at firmdl.c start says irritatingly:
*
* Set DEFAULTTTY to the serial device you want to use.
* Set the RCXTTY environment variable to override DEFAULTTTY.
*
probably the author meant setting the #define, not an env var when talking
about DEFAULTTY and mistyped RCXTTY later into RCX_PORT...
So set RCX_PORT in the environment and it will work.
