Maximum Data rate that could be used in Hyperterminal RRS feed

  • Question

  • Hi all,


    I am trying to connect an embedded system to Computer using a comport with Hyperterminal.  But the maximum data rate that I am able use is 115200 kbps.  Whenever I choose higher data rate in the hyperterminal, say 230400 kbps or 460800 kbps, it gives the error as follows:

    "Unable to open COM1.  Please check your port settings".


    Please help how to solve this problem.

  • What UART are you using?  If it's the 16550, then the maximum data rate is 115Kbps.
