ROM 1.0 Modem Firmware Bug

This Technical Note formerly discussed a bug involving buffering and serial port setting commands in the modem firmware in ROM 1.0.


Apple IIGS ROM 2.0 fixes a bug involving buffering and serial port setting commands in the modem firmware. You should not have to write a special case to handle this bug since it is reasonable to expect users to have the updated ROM which is offered as a free upgrade from Apple.
