I just downloaded and installed the NSPK trial on 2 computers to operate a cash drawer hooked to COM1 on one of the machines.  It is taking approx. 20 seconds for me to "pop" the cash drawer after the command is sent on my remote system.  Is this a normal delay ?

Well, to find out what is happening, we need to investigate your serial traffic.  
 
Usually we do it by means of PortMon program.
 
It is available by this link:
http://download.sysinternals.com/Files/PortMon.zip
 
Please configure it in such a way:
Edit -> Max Output Bytes -> 1024
Options -> Show Time [x]
Options -> Show Hex [x]
Options -> Clock Time [ ]
 
 
Experiment 1
============
 
Remote PC (physical COM port)
 
1) Launch portmon
2) Configure portmon to capture data from physical COM port: Capture -> Ports -> ...
3) Launch communications program and work with your device for some time. Then close communications program.
4) Save captured data to file: File -> Save As -> remote1.log
 
 
Experiment 2
============
 
Remote PC (physical COM port)
1) Launch NSPK and share physical COM port
2) Launch portmon
3) Configure portmon to capture data from physical COM port: Capture -> Ports -> ...
 
 
Local PC (virtual COM port)
1) Launch NSPK and create virtual COM port connector (redirected to physical COM port of the remote PC)
2) Launch portmon
3) Configure portmon to capture data from virtual COM port: Capture -> Ports -> ...
4) Launch communications program and work with your device for some time. Then close communications program.
5) Save captured data to file: File -> Save As -> local2.log
 
Remote PC (physical COM port)

Please send us there 3 log files: remote1.log, local2.log and remote2.log
