However, if I make an Open Driver call to open both the output and input ROM drivers, the program works fine, with no other changes. Anyone have any ideas WHY this is occurring? I would prefer to use the RAM serial drivers, but so far I have been unable. I am using a Mac 512E with a Dove 2meg and SCSI port upgrade (MacSnap 548S). I use, when developing, System 5.3 and Finder 6.0. And when checking the stand alone application at 2400 baud, I use System 6.0.1. Any help would be greatly appreciated, and if you need more info I can mail you portions of the source code for you check. Thanks. -- Sean 'Longstride' Penndorf !texsun!uokmax!srpenndo . . .----------- GEnie: S.PENNDORF | | `---. ---- The WEASEL Project ---- `--'LTIMATUM----'OFTWARE
