This includes communication boards, speech boards, A/D converters, etc. Remember that the DOS interrupt handlers aren't really talking to the hardware directly - they're going through Unix! Sun's answer to this is likely to be "use the Unix side" (e.g. run Kermit in a shelltool). I understand that this isn't always the answer though. - Glenn Roberts, The MITRE Corp., McLean VA (703) 883-6820 gfr@cobra.mitre.org
