Can you explain more detail about it? My test is : I download the Pharo 2.0 #20628 and i use the SerialPort class. The first time i do the code: | srl | srl := SerialPort new. srl close. srl openPort: 'COM1'. srl nextPutAll: #[ 27 66 2 2 ] . The RS232 device work fine. After the first time, when submit the same code the system answer: Error: Cannot open 'COM1' A this time i need to restart the Pharo environment. Any considerations, suggestions ?
