I'm searching for a solution to use the Win32::SerialPort with faster baud value as 115200 baud. The perl script works fine but to slow with Win32::SerialPort. So my idea is a faster com port communication up to 921600 baud. For my hardware I use a MAX rs232 converter with Mbaud range. On the other hand I ordered a USB2.0 - RS232 converter also with Mbaud driver for Windows. I tried to set the Baud value higher as 115200 baud. But all the time there appear an error massage like this one: 

Could not set baudrate on com2 at serielle2gui2.pl line 5304
Missing REQUIRED setting for BAUD at serielle2gui2.pl line 5318
write_settings failed, closing port at serielle2gui2.pl line 5318
