You can use a super serial card with interrupts on a IIgs or //e or whatever
but the software has to handle the interrupts properly.  My own program Talk
is Cheap can enable the super serial card at up to 19,200 baud but the actual
throughput is limited to around 9000 baud or so due to lack of CPU speed to
handle faster with much useful work being done between characters receieved. 
Software that doesn't follow the rules regarding installation of interrupt
handlers and so forth (which includes most other Apple // telecom packages)
will cause trouble on the IIgs though, particularly if AppleTalk is enabled so
you have to know about the particular software in use to know if you'll be
able to use interrupts on the IIgs for telecom.
