It's ugly, but it should solve your near term problem. Long term, I wasn't planning on (nor do I have the resources to) rework the device drivers for all of the UART's to support the new API -- I was just going to define the API and implement it for the UART(s?) that I use. --wpd > -----Original Message----- > From: Giri Raja [mailto:giri_amf@yahoo.com] > Sent: Wednesday, August 04, 2004 4:14 PM > To: ecos-discuss@ecos.sourceware.org > Cc: Doyle, Patrick > Subject: RE: [ECOS] wiggle with the CTS pin > > > Thanks Doyle.
