Error -98 is  portNotCf  in Apple's header filer MacErrors.h:

portNotPwr = -96 /*serial port not currently powered*/
portInUse  = -97 /*driver Open error code (port is in use)*/
portNotCf  = -98 /*driver Open error code (parameter RAM not configured 
for this connection)*/

I don't know what that really means, but we are a little further ahead 
in understanding the Keyspan problem.


If you comment out 8 lines of my previously-posted TermGetStatus 
override fn, it will not try to open for output.  You can then discover 
whether it succeeds in opening for input:

//ioErr = fn PBOpenSync( pb ) // try open for output
//long if ioErr
//stop "Error " + str$( ioErr ) + " opening output"
//termStatus = 2 // open already
//xelse
//ioErr = fn PBCloseSync( pb ) // close output
//if ioErr then stop "Error " + str$( ioErr ) + " closing output"
pb.ioNamePtr& = @gFBSerialInName$(-serPort)
pb.ioRefNum%  = 0
pb.ioPermssn` = _fsRdPerm
ioErr = fn PBOpenSync( pb ) // try open for input
long if ioErr
stop "Error " + str$( ioErr ) + " opening input"
termStatus = 2 // open already
xelse
ioErr = fn PBCloseSync( pb ) // close input
if ioErr then stop "Error " + str$( ioErr ) + " closing input"
end if
//end if
