How would DC power affect our issue though???
As for VPN, don't I need a *serial* connection to reproduce the problem? Aren't you testing using serial connections for both Hypterterminal and Absolute? See my post (two back) I think you may have missed one.
Brian
It always helps to read before opening my mouth. I get it now. The DC powered version requires a separate DC adapter (sold separately).
Brian
Yes, I'm using serial connections for my testing.
I was thinking I could allow you to remote control a workstation that has a serial connection to the switch.
Allowing me to VPN in will let me do some preliminary poking around using a serial port monitor, but if additional debugging is required, I'll have to lay hands on the hardware. If you're really interested in doing this, give me more details by mail: (bpence at celestialsoftware.net)
If you're interested in peeking under the hood of the internals of the serial communcation, try Portmon from sysinternals. It's not something I'd expect you to do, but if you have the interest and the time you might want to take a look. Monitor a session using Hyperterminal and one with Absolute.
See if there are any differences in how the serial communication is handled. There's another switch coming up in about 4 hours that's still a reasonable price. If I can pick it up cheap, it won't be a complete waste. I can always integrate it into my home network. Will this thing run in a hot attic? Brian
lost another one... How about this one <old link removed>? It looks the same, but without the expansion ports. Still waiting on VPN info.... Brian
I think that switch would work, but let's try the VPN idea before spending any cash. I'm not sure how heat resistant the switches would be, an attic can be a pretty hostile environment.
I'll send you an email about the VPN.
Question:
Is Hyperterminal running with flow control set to 'hardware' or 'none'???
This last question is still open. Was hyperterminal running with 'none' or 'hardware' flow control? I'm still trying to come to grips with the differences in behavior between the two.
When both are running with hardware flow control, there should be very little difference in the behavior of the two, as the serial control settings are *almost* (but not quite) identical.
On the 2924M-XL, flow-control was set to hardware. (This is the model that shows no output if flow control is set to none.)
On a 3550, I can reproduce the truncated output using hardware or none.
The question was about Hyperterminal, not Absolute. I was under the impression that Hyperterminal might be running with flow control set to 'none'.
Try with both (none and hardware) on hyperterminal and let me know if there's a difference.
Brian
This morning I tried Hyperterminal with a 2924M-XL configuring flow control as none and hardware. I don't notice any difference. Both settings work equally well with no truncating issues.
I see you have a new version for me to try in our other thread. I'll try it and report back.
Version 3.68 fixed the truncating issue in both (hardware and none) flow control modes.
Thanks for the excllent support!
Great job Brian!
I'm glad we finally got to the bottom of this one!!!
Hyperterminal has its roots in serial communication, so I trust its behavior is probably more accurate. AbsoluteTelnet started as a telnet client and then added serial/modem/ssh1/ssh2 later.
I'm going to run this version by some other users who also do serial communication just to make sure we didn't break anything...
Thanks for you help and testing! I *am* glad I didn't have to buy any hardware!
Brian
