| In most cases, the <Enter> key is normally associated with the carriage return, which is denoted by ASCII character 13.

| The equivalent hexadecimal sequence of <cr><lf> is 0x0D 0x0A, or if you want in decimal, 13,10. Just send this using SBUF and it will work.

| The last time I coded in BASIC is at least a decade ago. Anyway, I remember BASIC uses the chr$(13) function. Not too sure about PICBASIC. According to here, they did mention a chr() function. Probably it's the same.
