serial port monitor and playback

We are trying to debug the data stream coming from a medical monitor to pc-based software through a serial port (com1)

We need to record the data stream (it is a binary data stream, not ASCII), look at it, and be able to play it back (out com2, through a null modem, back into com1) to mimic the original data stream.

Have downloaded HHD Software- Serial Monitor Ultimate and also Eltima Serial Port Monitor.  HHD Software looks more powerful, but can't get either to play the data stream back out com2.  Tried copy /b log.bin com2
but device driver on com1 didn't see anything connected ("CTS low on COM1)

Any suggestions, or better software for accomplishing this?

It's been a while but I used to use a utility called SerialSniffer to do this in a Biometrics Lab
This seems to be the current Iteration of the same product, not sure if the unregistered version will give you enough capture to see if it's what you need though but used to input live data and then playback from the capture machine to emulate this.

Purchased the base module and the recording module and the virtual port module.
Can record what looks to be the binary data.
But when I go to play back, I get error "Comport A is not open for serial connection"

Even when I attach Comport A to a virtual port.
Based on the instructions, we are supposed to be able to playback to a virtual port and connect our application to this.

Any ideas.  I'll email to serialsniffer.com, but that will probably take days.

Will your db performance match your db growth?

In Percona’s white paper “Performance at Scale: Keeping Your Database on Its Toes,” we take a high-level approach to what you need to think about when planning for database scalability.

Like I said it's a while since I was using it (EMG recording) I remember we needed two licences, one to record and one to emulate the playback port but it worked fine. I guess we need to wait until after the holiday.  Can ring the lab and see what they're using but no one there until Tues.

Right.  I purchased both additional modules--- the base program, Module A (recorder) and Module B the Virtual Serial Port module.
Not many people know about debugging serial ports anymore-- any help you can provide after the holiday is greatly appreciated.

In Serialsniffer you must "start" the Comport that you are playing back from.  Start means connect to a serial port.  Same start that you use to listen (sniff) a serial port.

Now it is playing back nicely.  Good program.
Thanks.
