• ZylSerialPort is a Delphi & C++Builder thread based serial port component. Use ZylSerialPort component to easily communicate with external devices on serial port connection, such as modems, bar code readers, GSM modules and others. It works in synchronous and asynchronous mode.
• Delphi and C Builder component for serial communication for. Send (write) or get (read) bytes to the parallel port (lpt1 or printer port). I recently had to dig this up, and noticed it didn t work in my Delphi XE, which Reading binary data from serial port using Dejan TComport Delphi component.

A few years back for one of my applications I moved my serial handling to a thread when a certain app had to respond very quickly to certain serial events.

It was in BDS2006, with an older version (some 3.x?) It was done by having code like this in the tthread.execute:

Initialization was like

The rxchar method reads using comport1.readstr() H264 codecs download for winamp free.

I recently had to dig this up, and noticed it didn't work in my Delphi XE, which has tcomport4. Looking in the source I saw remarks thatcomport4 has changed the way it deals with its internal threads ('overlapped' property), but the default seems to be 'true' has a comment 'classic', and I

assumed that means compatible with older versions.

Note that the protocols are binary, and all string,char<-> ansistring,ansichar changes have been done like I did in the normal mainthread version

Now the real questions:

1. does anybody have tcomport4 working in a thread ?
2. Are there obvious mistakes in the above?
3. or do I need to migrate to a different component?

I'm still debugging what is going on, but am in a hurry, which is while I post this in the hope of quickly getting pointers.

Update

I reinstalled an old turbo delphi copy, and verified it worked there with v3. I fixed a small bug though in the codepath that went a bit different from what I thought (not in the above code)

This allows me to describe the behaviour between dxe/comportv4 and bds2006/comportv3 better; the v4 code generates much more read events (hundreds/second). It seems that the read doesn't delete the read chars from the incoming queue or so.

Update 2

I did a quick test with the newest version, and did the necessary rearranging (kill string function use for an essentially binary protocol). I got stuck for a while because the application crashed on startup, but that is because I use gnugettext, and Comport packages a different (non unicode even?) version. But after that it works.

Unfortunately the changes are a bit to risky to propagate back to the production version (completely written protocol decoding), so I'll have to test with inbetween versions (between 4.0 and 4.11f). I'll do that in due time, any suggestion which version was the last readstr(ansistring) one?

Update 3

In the end I simply renamed the 4.11f units and use them in parallel to the old version, using the 4.11f for the threaded codebases and the old one to maintain existing code.

Long term I might simply take the waitforevent code and make an own version. The main problem with it is that it is afaik not possible to see if the wait terminated on timeout, stopevent or whatever. This means you need another timer if you want to e.g. send on regular intervals.

You need to upgrade to the latest stable 4.11 release here.

You need to add these folders of the installation to your library path (for 32 bits platform):

for 64 bits platform you need to add:

and if you want to debug the components these to:

Already I have found the problem

In the project, it was referring to a unit that had included your (Cadetill class) class TWebControl. In GMLib you turn it to using, but a more modern version, in which now you include TCustomWeb, which before would not be
