Programming :: Print A Single Digit Integer On To The Screen Using The Int 0x80?

I want to print a single digit integer on to the screen using the int 0x80. I have loaded the number in the ecx(=5, say), size in edx (=4, lenght) and eax (=4) ebx (=1). I've added 48 to the contents of ecx, and then calling int 0x80, I thought should print 5 on the screen.

However it does not print anything. also gives no errors. I checked the contents of the ecx reg (gdb), it has 53.

A snippet showing the this will be great. I've seen snippets using the c library (printf), but I want to see how it is done using int 0x80.
