correct is...

pc.printf("%d \n", pos);

okay, that seems to have worked partially, now it doesnt even print H which appears before the correction

It will be printing the H but on the same line as the number with no spaces between them. If you want a new line you need to include either \n or \r\n, (unix or DOS line endings, most terminals have an option to select which on to expect.)
