Hey Jim 
At my CBM610 I first successfully connected an old analogue modem to the existing CBM610 RS232 interface.
But the CBM610 has the disadvantage that it needs the signals
RTS-CTS (PIN 4-5) and DSR-DTR-DCD (PIN 6-8-20)
Can I just solder the necessary "pin" together in an external adapter?
I have now bought a WIMODEM232 modem and tested successfully with another adapter at an C64.
But the WIMODEM232 does not want to work on the CBM610.
The 2.0 version has no more adjustable solder bridges.
What can I do anyway? Thank you
This is the picture from my analoge Modem, where i solder itself at the DSUB25 Modem connector:
