setserial alternative

Hello!
Perhaps a bit offtopic, but could Ioninja perform some configurations similars to what "setserial" does?
The reason it that I have working with a Moxa RS232/485/422 device (UPORT 1250), and the mode (232/485/422) is configured using setserial (eg. setserial /dev/ttyUSB0 port 1). It would be useful to me to be able to configure it from inside ioninja (and to be franc, it would solve a problem I currently have, as I am not able to make setserial work well in my ARM device... any idea would be welcome :-)).
Regards!
Thank you
