As Charles has stated, in C#, an identifier must start with either a letter or an underscore. So, you have some options:
1. Use an enum, change name to something like "Baud1200" or "_1200".
2. Use enum, name as above but add the EnumDisplayValue attribute to the enum items to explicitly provide the display value. This is in MicroFour.StrataFrame.Tools namespace.
using MicroFour.StataFrame.Tools;
public enum BaudRateVal
{
[EnumDisplayValue("1200")]
Baud1200,
[EnumDisplayValue("2400")]
Baud2400,
[EnumDisplayValue("4800")]
Baud4800,
[EnumDisplayValue("9600")]
Baud9600,
[EnumDisplayValue("19200")]
Baud19200,
[EnumDisplayValue("38400")]
Baud38400,
[EnumDisplayValue("57600")]
Baud57600,
[EnumDisplayValue("115200")]
Baud115200,
[EnumDisplayValue("230400")]
Baud230400
}
3. Add a table with the Baud rates, then fill the combo with a BO instead of an enum.
Hope that helped!
