串口通信时接收数据总是收收停停~这是怎么回事？用的是两台电脑串口通信的调试，16进制发送，周期是30MS，接收端电脑总是会停几秒钟继续收

Hi,

For VISA Read, there is a Byte Count input. If you wire more than 0 to it, it will waits for N number of bytes available at the port before performing a read.

However, if N number of bytes does not meets, if will timeout after a moment.

Hope this helps in one way or another.
