Yes, both writes are succeeding. I don't have a jig or anything to actually verify the serial output. The only thing I have is the actual serial device spitting out a "Command too long" error. > Does your device require a constant byte stream, with no delays between > characters within a single "command"? Unknown. I'll research this more. How long of a delay is getting inserted here? Certainly not very much by serial standards. I would have a hard time believing that the serial device is aware of the two writes. My guess is that there are extra padding bits getting placed somewhere. -- (__) Doug Alcorn - Unix/Linux/Web Developing oo / PGP 02B3 1E26 BCF2 9AAF 93F1 61D7 450C B264 3E63 D543 |_/ mailto:[EMAIL PROTECTED] http://www.lathi.net _______________________________________________________________ Don't miss the 2002 Sprint PCS Application Developer's Conference August 25-28 in Las Vegas - http://devcon.sprintpcs.com/adp/index.cfm?source=osdntextlink _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-users
