There are actually 2 serial ports, usually 1 set for the printer,
and 1 for the modem.  They can be set several ways:
 
1)  By Default from Rom at boot-up.
 
2)  Using the Apple IIc System Utilities disk.  If you don't have
it, you can get it from The ByteWorks (manuals, too), an Apple II
Users' Group, or from one of the Apple ftp sites.
 
3)  Directly from the Word Processor or Telecom program you use.
The manuals for those programs should tell you how to change the
settings.
