That's fairly normal for SCO.
Your uucp/Devices entries should look something like
Direct ttyc02 - 38400 direct
ACU ttyC02 - 38400 zoom \D
If both ttyc02 and ttC02 are disabled you can "cu -l ttyc02 dir"

The DB25 boxes provide all the signals you need. Check you cable
abd make sure you have at least pins 1-8 & 20. The Digi is DTE so
it's straight through to the modem (DCE). And make sure the Digi
drivers are up to date. (mpi ver. 3.2.1)

Perhaps zoom has docs on their web site.
If all else fails, undo your ditty commands and try a MultiTech modem.
