[comp.sys.mac.hardware] Adding an extra serial port?

xzoy@vax5.cit.cornell.edu (06/29/90)

Does anybody out there have any experience with adding additional serial ports
to a Macintosh (any kind of Mac)? I'm curious to know if this can be done and
if it can to find out other people's experiences with companies and brands.
Thanks in advance for any input!
