Hello NG, I wanted to configure Monitor. So I followed the steps described in "/Keil/C166/Monitor/Readme.txt". I decided to use the UART ASC0 mode and put CODE_START in "Config.inc" to 000200H (rom, after the vectors). The problem is that there are no vectors (i.e. no jump to start at 0, no jump to NMI at 8, ...) What I made wrong? Thanks - Peter
