Hi Marcelo,

nothing...

A comment saying why it's not perfect would be nice... ;)

Hi Dimi,

It's not perfect because TransmitCommChar should bypass the Linux 
kernel's internal transmit buffer as well as any pending overlapped 
operations. The characters should be treated the same way as a flow 
control character.

Unfortunately, that probably requires a hack in the serial driver. 
Actually I should get all these hacks together (including the one for 
polling on RTS,DTR,CD,RI deltas) and submit a patch for Linux 2.5.*... 
in my copious amounts of spare time ;-)

That'd be real nice, as there was much talk in modifying the serial driver
some time ago. It also looks like the kernel people are willing to help out
Wine. Since we've missed 2.4, maybe we can get them in in time for 2.6 :)

If i send this char to the end of current sended string..

something like writefile

i need a way to send this char to serial, and i can't call writefile directly

anybody help me...????

I have a serial printer used in Point-of-Sale and the factory software needs this F$@*# function.

thanks

Marcelo

Hi Marcelo,

1. apply my patch
2. test the program
3. if it doesn't work, send me marcelo.log.gz from

wine -debugmsg +file,+comm,+server app.exe > marcelo.log

obrigado,

Mike
