Can someone confirm that the ph_com commands work with COM ports >5?

been having the same problem but thought nothing of it because lots of software can't deal with comports > 5
But since you've started this I would like to submit this to Dave as a part of the next beta wishlist...

support for comports > 5

OK, something strange is going on...

I changed the port to COM2, and it still does not work. Using HyperTerminal works fine.

First I do this...
Code:
ph_comopen( 3, 2, 9600, "N", 8, 1, 1, 0, 0, 1, 0, 1, 1, "?", "CID2" )


Which returns 0, then I do this...

Code:
ph_comsendstring( 3, "@01" )


Which returns 0, but does not actually send any data.

Tony and Peter,

I reviewed the ph_com code and you should be able to use any valid COM port number (I believe COM256 is the max). However, it's got to be a COM port that the Microsoft COMM control recognizes. It seems that depending upon the port, the MS Comm Control sometimes cant see it.

Tony, this looks like your CID functionality. Was it working and suddenly stopped? Based upon your above pasted code, I don't see any problems and it looks as if it should work. Have you done any further testing?

Dave.

I added a quad mux for my cams and it has a serial port for control, so I added a USB-232 adapter. It's one-way comms, so I just left that CID macro ID in there since I copied the ph_comopen from the CID stuff.

I started with it on COM6 then moved it to COM2.

What else can I try?

Tony,

Oopps, sorry Tony .

Im not sure if I remember or not, but have you written stuff in VB using the Microsoft VB6 COMM control in the past?

If so, do you think you might be able to setup a quick test and determine if it truly is a problem with the Microsoft COMM control. My best guess (based upon past experience) is that the MS control cant always see some USB to 232 adaptors. I had one that was not recognizable (cant remember the brand, but took it back). Got a different brand, and this one I can see.

PS...Ive been tracking the thread between you and Peter on the Weather Underground macro. You are going to love the next beta since Ive gone ahead and included some new functions that allow you to do this type of HTML parsing a lot easier (including regular expressions .

Dave.

Yeah, I have written VB6 comm stuff, but...

This one of two Radio Shack USB/232 units I have. The first one is for my W800.

Parsing and reg ex? Cool!

Hmmm...

It works using HyperTerminal and you have another one just like it currently running your W800. So that would rule out a bad unit and the Microsoft COMM Control. Im stumped.

You say that when you execute the ph_comsendstring(3,"@01") function you get a 0 but no data is actually sent. How are you monitoring the actual data? Are you able to send other strings to verify that nothing is getting out at all?

Dave.

Correct. I do the ph_comsendstring(3,"@01"), get a 0, and the mux should switch to input number one, but it does not. Firing up Hyperterm and typing "@01" switches it.

Other commands I've tried: @MU, @22. I'll try some others tonight.

Maybe the "@xx" is killing it?

Also, if I try to open the port without the USB/232 connected, it bombs, so it is seeing it when it's there.

I just tried other commands and other COM control numbers with no luck. I even tried to disable RTS and DTR (just to see).

Could there be a problem specifying a macro that is already being called for characters received from another COM port?

Tony,

Should be no problem to call the same macro from multiple COM controls. The macro ID is just a stored string that ultimately is just passed to a ph_macro function.

Im just wondering if the @ symbol is causing problems (it shouldnt, but what do I know ). Try escaping it with \064. So your formula would be:

ph_comsendstring(3,"\06401")

Let me know,

Dave.

Ratsa frasta grumble...

It was a speed issue! Sending the string was too fast for the mux. Adding an intercharacter delay of 25ms fixed it.

Yeah, sorry! When the "\064" didn't fix it I got irritated and thought harder!
