Jemplode will not find empeg.

I have 2 beta 11 with Hijack, using serial, Windows 98. 2 beta 11 Jemplode can not find the empeg. I know it's a good connection because Rio Emplode finds it. What am I doing wrong?

On the Jemplode page there is a link to a "serial faq"...

... which, if I'd bothered to read it before shooting my mouth off says that it should just work if you're under Windows.

Mike!!!!

I've done it finewith win2K.... Does anything else have your serial port? (An open Logo Editor or Hyperterminal)?

I don't think so, I just tried it with no other programs running and it still won't work.

It takes a few seconds to find it, its not as fast as emplode. Try manually inputting the ip of your empeg.

Try manually inputting the ip of your empeg.

An IP for a serial connection. Now that'd be an interesting trick.

Yeah. I don't have ethernet set up.

Doh this is what i get for skimming posts. (ppp over serial uses an ip, doesnt it?)

Sure does. And, in fact, many WAN connections are referred to as serial connections, and they definitely have IP addresses. But you know what he means.

Can you connect with HyperTerminal?

I don't know. To tell you the truth, I don't even know what Hyperterminal is.

Is there somewhere to select what com to look under in Jemplode? I didn't see any place to set it, maybe it's set on the wrong one. Or is it just by default com 1?

Just noticed that Brad had already asked you this ... I would see if you can communicate with the Empeg over Serial _at all_ then come back to jEmplode. Check the RioCar FAQ for how to use HyperTerminal...

Alright I got Hyperterminal to find it while booting up, but it won't let me type commands in. Like in the faq, it says you can type N and press enter and it should goto to the next track. But it does nothing.

When you say you got Hyperterminal to "find it" while booting up, what exactly do you mean? It sounds like you've got more sinister serial port issues ... You're kind of on your own figuring those out, but if you get to the point where your serial connection works consistently, try out jEmplode again and let me know how it goes.

I mean it says this when I plug in the empeg:

After that, I can't control it or anything.

I said earlier that Emplode would work fine with the serial, just not Jempeg, but now I can't even get Emplode to find it.

Any ideas?

I'm not sure if you already knew this, or if I already made it clear - so I appologize if that's the case, BUT only one program can have a "hold" of the serial connection at a time. So, if you are viewing that output from Hyperterminal and still have that program open, no other program will be able to use the serial connection. The same goes for the Logo editor or anything else. Once any program is using that serial port - no other program will be able to "share" it. Also, I've noticed that Jemplode takes longer to find the RioCar than emplode (so sometimes it looks like the connection is going to fail but it doesn't). Finally, there were a few times that I had to restart Jemplode to get it to find my player (esp. after changing any of the connection options).

Out of curiousity, why are you using serial? I only use it when using Tony's Logo editor or when sending escher.raw and logo.raw files (and applying player upgrades).

Ah -- I missed the one where you said that Emplode can connect with serial

Are you just running with jemplode20.jar, or are you running with a real install of jEmpeg? (i.e. are you running the Exe from the actual installer?)

Yeah, I understood you. I made sure no other programs were running that would use the serial. When I try to connect via serial to emplode now it just keeps searching indefinitely. On Jemplode it just says "No empegs were found" after about half a sec. I was using serial on Jempeg cause I don't have ethernet set up. I was using it on RIo Emplode just to see if it would find it.

I've tried both. One is Jemplode Version 2.0b11 (opened from the start menu) and the other is Jemplode Version 34. I used the installer for one of them, I think the one in the start menu.

Maybe one of those programs isn't really shutting down? Did you re-boot?

Just tried rebooting. No luck.

In that big list of stuff from Hyperterminal it says:
SA1100 serial driver version 4.27 with no serial options enabled

Is that anything worth noting?

Nah. Ignore that line, it's normal. It just means that the kernel driver for the serial port built into the StrongARM chip was compiled with no extra options turned on.

Alright it works with Logo Editor. But not like it used to. I used to be able to press 'Send to player' and it would send it right away. Now it gets a ComError in readbyte24 and I have to unplug the player, plug it back in and then it sends the logos fine.

hmm....

When that sort of thing started happening on my system, it was a frayed serial cable. I had to discard it and use a fresh cable, and all was well after that.
