INT 21 - DOS 1+ - READ CHARACTER FROM STANDARD INPUT, WITH ECHO

	AH = 01h
Return: AL = character read
Notes:	^C/^Break are checked, and INT 23 executed if read
	^P toggles the DOS-internal echo-to-printer flag
	^Z is not interpreted, thus not causing an EOF if input is redirected
	character is echoed to standard output
	standard input is always the keyboard and standard output the screen
	  under DOS 1.x, but they may be redirected under DOS 2+
