Not that I'm aware of, but there are a few things you can do to try and pinpoint the source of the error and thus correct it. In the serial driver code, drivers/macintosh/macserial.c, are lines like these: 119 /* 120 * Debugging. 121 */ 122 #undef SERIAL_DEBUG_INTR 123 #undef SERIAL_DEBUG_OPEN 124 #undef SERIAL_DEBUG_FLOW 125 #undef SERIAL_DEBUG_POWER 126 #undef SERIAL_DEBUG_THROTTLE 127 #undef SERIAL_DEBUG_STOP 128 #undef SERIAL_DEBUG_BAUDS (from <http://lxr.linux.no/source/drivers/macintosh/macserial.c>). By defining these symbols and re-compiling the module (or kernel), then you may be more apt to determine the exact cause of the error. Elizabeth
