initialize serial port

When my Windows 7 install boots up, I can't access my Serial Ports from the command prompt.


If I send "ECHO NET 4 >Com4"

I get nothing.


If I open a terminal program, such as Hyperterm Private, and access the port, then close the terminal program and send:

"ECHO NET 4 >Com4"


Then it behaves as I would like it to.


It's like a terminal program 'wakes up' the com port or serial port.


Any way I can waken the port without opening a terminal program to do it?



HyperTerminal isn't included in this version of Windows.


For more information, refer to the link.


What happened to HyperTerminal?


You may contact Hilgraeve Support for further assistance on this issue.


Hope it helps.
