[PCR-1000] PCR-1000 Maximum Scan Rates

[Julian Blandford]

In the recent flurry of messages about TalkPCR I noticed that Probe1k laid claim to having the 
fastest scan rates of any software that can drive the PCR-1000. 

Apparently this is due to it being DOS based, nice and simple and having a great database 
engine under the hood which enables Probe1k to churn through the frequencies quicker. 

So what is the limiting factor on the maximum scan rate of the PCR-1000? Is it simply the 
comms interface speed? 

Presumably with faster and faster PC hardware out there that can execute code quickly (no matter 
what GUI or database engine is being used), the limiting factor would not be the program 
that generates the ASCII going down to the PCR? 

Do those little USB-to-serial interfaces improve the throughput over just a plain DB9 connection? 

best rgds, Julian
