Dear Sir, I have read Project Description but really need more detailed requirements or at least high level features to estimate it precisely, because based on the project description, I can't estimate. Please contact me for portfolio or further discussion about your project, also, my current bid is just a placeholder. Look forward to hearing from you. Regards, HuyPQ.

Hello. I have been many experiences of VB or Qt app that it connects the terminal device and it communicates by 232 COM port. Perhaps your medical device have certain communication protocol. Already I communicate with terminal device by Mod-bus or myself-protocol. I want to know its protocol for your project. Then I'll finished this job for a short time. If you are interest then let's chat before you award me. Thanks!
