As I previously set the RCSTA.1 = 1, I wrongly thought this would handle the automatic overrun. I should have noticed the "Read-Only" flag on this bit in the datasheet.
BTW, what exactly does "DEFINE HSER_CLROERR" 1 do? Where can I find information about what other DEFINE commands do?
NB: my apologise Demon; I missed your advice for a pull-up in an early post

From the book "As the hardware buffer only has 2 byte input buffer, it can easily overflow if charactors are not read from it often enough. When this happens, the USART stops accepting new characters and needs to be reset. This error can be reset by toggling the CREN bit in the RCSTA register. A DEFINE can be used to automatically clear this error. However you will not know that an error has occured and characters may have been lost."
