rs_ioctl() in sgiserial.c info/help needed

["Randy Sartin" <randys@ridgerun.com>]

Background:
I am trying to get the Indy's serial port to drive a dongle and am having
some trouble getting the dongle to work. The problem seems to be in
rs_ioctl() in sgiserial.c - it doesn't handle the TIOCMSET command. The
TIOCMSET command allows control over the DTR and RTS lines.

The "standard" rs_ioctl() in serial.c does support TIOCMSET. It calls
set_modem_info() to control the UART (I think) to then control DTR and RTS.

So - my question is...
Can I control DTR and RTS on Indy or is this a software feature that hasn't
been implemented yet?

Thanks,
