Hi Anish, Are you getting the timeout after the select() or the write() in hpiod?
If you are getting the timeout after the write(), you may be losing data when you close(endpoint_fd) between retries. The write() may timeout after writing a partial buffer. Then the close() will kill any remaining partial buffer. -dave > -----Original Message----- > From: Anish Mistry [mailto:[EMAIL PROTECTED] > Sent: Wednesday, June 07, 2006 7:46 PM > To: Suffield, David > Cc: hplip-devel@lists.sourceforge.net > Subject: Re: [HPLIP-Devel] FreeBSD Porting > > > On Tuesday 25 April 2006 18:11, Suffield, David wrote: > > Hi Anish, > > I appreciate your FreeBSD support.
