Message-ID: <134@iravcl.ira.uka.de> Date: 20 May 88 11:57:52 GMT Lines: 22 Posted: Fri May 20 12:57:52 1988 Organisation: Universitaet Karlsruhe, IRA, F.R. Germany A nice guy recently told me about the MS-DOS-Interrupt 2Fh. He said it may be used to communicate with memory-resident programs. My problem is: that's a DOS internal int. and therefore it is not documented. The only documentation I found is something about the way PRINT.COM uses this interrupt, but not more. Is this the legal way to communicate with memory-resident programs beside using own interrupt-numbers ? Who can help me ? Thanks in advance ... marvin. P.S.: I'am working with MS-DOS 3.3 =================== Ludger Wetzel = Hirschstrasse 103 = D-7500 Karlsruhe = West-Germany = ===================
