Hi,
I've just started playing with the SDCC "C" compiler (downloaded from www.pjrc.com) and I'm having a lot of trouble getting serial I/O using ser_ir.c working. I've written a short program that just sends "TEST" to the serial port, but I'm only seeing the first character on my PC. Anyone care to make a guess as to what's going wrong? BTW, I'm using a Dallas Semiconductor DS89C420 "A2" engineering sample.

Thanks.
Phil.
