Subject: Com port access on Zenith H8

I have been given a Heath/Zenith H8 (8080 based) with some software 
(kermit, basic, fortran, maybe C but I haven't found it yet). 

I am interested in accessing the com port in this system programmitically.
Is there anything like the IBM BIOS calls that read and write one char to 
the com port like there are on DOS systems??

I have manuals for BASIC, and FORTRAN, and they do not mention anything
about opening the COM port as a file. Attempting to do this (the Com port
has a name something with a colon) gave a bad disk file name error, so I 
assume that open is disk-oriented only.

Any ideas? I can access the com port through kermit, but obviously this 
isn't all i'm after here.
