#81622 - Delays
Responding to: ???'s previous message
Russell.

Sometimes MsComm controll turn very slowly serial port communication, I don't know exactly why, but sometimes delays works fine...the our friend problem is not very clear too, if he use OnComm routine, there will be not problems, just he wrote that recieve 67,68,69,66 instead 66,67,68,69 I think he's not taking enought care after recieve bytes and processing them. (It is difficult to see without all Vb code in hands ).
so delays at 8051 code will give him more time to do (I don't know what ??) in the VB code.

Can you imagine ....if he's not using ISR at 8051 ...what could happend if he want to send from VB another character back to the MCU ???

Full handshaking with the poll method that you said, could be great !!!! of course.
Best Regards.
