Hi Robert,
if I'm not wrong, the command line parameters are overwritten by the
config file (maybe you should look into syslog for possible errors). So,
if you want to have as much as possible information about SER failure,
uncomment in your ser.cfg the part for debugging mode (starts with "/*
Uncomment these lines to enter debugging mode").
Than try to start again ser and see what's wrong (if any).
regards,
Marian
