Hi All,
Anybody any ideas on why a board I am working on using a PIC with a USB not appear totally in the Serial Port buffer, I am expecting SN=12345678 but can get SN=123 I'm guessing it is framing on the data bits, I have never seen this with similar boards though. If I use a timer will this be certain to avoid the problem, sadly in the past using timers has led to " well it works on my machine, why not yours". I am thinking the interupt handler is missing some data, or may be the board is not sending all of it?

You're trying to retrieve a serial number sent by a device with a USB virtual serial port but you're not seeing all of the data?
Post the relevant code and maybe someone will see something.
