Serial port errors
Hi!!
This is my first time here. First of all, thanks to you folks for this great
piece of software.
My problem is as follows:
I'm using a VisualBasic 6.0 application on Linux using wine 0.9.58. This
application has some menus showing some icons so users can click on them using
a serial port device made by a friend of mine, through serial port, which acts
as a "keyboard". Serial port is connected to com1 symlinking it from
/dev/ttyS0. Everything works fine, except that sometimes, apparently randomly,
application freezes when changing from one screen to another, having to wait
many seconds for it to continue it's execution.
The best I have been able to do is to make the application run faster in
general, so this time gets shorter, but we are still speaking of many seconds.
Some information about the application: it reads and writes data from and to
the serial port, using 9600 baud rate, com1. It opens it, reads the
information, changes the screen or menu, and then closes the port again. It
does so many times during the execution. Everything works fine on Windows XP.
Can anyone help??
I attach some debugging information. Original file, using
"WINEDEBUG=trace+comm" was 100MiB sized, so I have just cut and pasted the more
relevant into the file
