Hyperterminal loopback test

Posts: 12,537
I wanted to verify that I could use a higher baud rate with my computer and hyperterminal as I have a BS24px.
I have an ASUS computer with WindowsXP.
I cannot seem to find a way to get the loopback to function properly.· I Googled a proceedure that calls for a configuration of 'Direct to Com1', but I cannot locate that as a menu choice.
Can anyone who has sucessfully done this advise me?

As you configure Hyperterminal, you can make a choice for "handshaking" or "flow control". Make sure its set for "none" otherwise the Hyperterminal will either expect RTS and CTS to be joined on the connector, or will expect a software "ok to send" signal in the data string.
The "Direct to Com1" is sometimes just "COM1" on the newer versions.

The 'dongle' has been already made and in place, but not working due to apparent software complexities.
Handshaking is all off [noparse][[/noparse]aka 'none'].
I will recheck my dongle for continuity.
I guess I can stop looking for a way to get 'Direct to Com1' and just accept that 'Com1' is it.
I have tried Hyperterminal and another software called Terminal.
I begin to wonder if this is a Half-duplex versus Full-duplex issue OR if there is some hidden buffer OR some BIOS issue.
I am not using USB, just the generic RS-232 Com1 on the motherboard.
Also, I am about to make a more complex loopback dongle [noparse][[/noparse]including all the handshaking signals] so that I can run future diagnostics.
Seems to me that having a loopback dongle provides the ideal trainer mode for Hyperterminal as you don't have to ponder if another device is contribuitng to difficulties.
Terminal is nice friendly software because it has a Sent Window and a Recieved Window. It allows for more adjustments than Hyperterminal and is a free download.

I have tested my Loopback at 256,000 baud and all is well.
Just connecting Pin 2 and 3 did not create a proper hardware set up for a Loopback Test.
I created another 'dongle' [noparse][[/noparse]test plug] that uses 8 of the DB9's nine lines -- only line 5 was omited.
Pin 2 to Pin 3
Pin 8 to Pin 7
Pin 1 to Pin 6 to Pin 4 to Pin 9
This one works fine and I did NOT locate any software issues, BIOs issues, or half-duplex versus full-duplex issues.
Seems to be a purely hardware problem of not having something in the Pin1/Pin 6/Pin 4/Pin 9 hooked up.
