Title: SLOW Post by jace on Oct 22nd, 2008, 1:53pm 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 ? |
