I believe they did do a TCP/IP add on (or bought it in).

I found this:

« Currently, the DESQview/X Network Manager can communicate using the following network APIs and network software: NetBIOS, Novell Netware IPX/SPX, FTP Systems PC/TCP, and Novell's LAN WorkPlace for DOS. Check with Quarterdeck Office Systems for an up-to-date list of network APIs/software supported. »

I never even looked at clock interrupts, but you're right.

https://en.wikipedia.org/wiki/BIOS_interrupt_call#Interrupt_table

« 08h This is the real time clock interrupt. It fires 18.2 times/second. »

Couldn't quickly see anything about CDOS, though.
