Try upgrading dosemu from CVS, its
serial code should be much faster.

You don't have to set $_ports, you
should use $_com1 instead. Well, if
you want a direct access, you have
to disable $_com1 and use
"device /dev/null", that option basically
does nothing.

> fast ox03f8"
That should be 0x3f8, not ox03f8
And you normally should not use $_ports
at all.

Write that to $_ports string instead of

Re: Port Access slow

[gede]

I have added
$_com1 "/dev/ttyS0"
$_ports = "device /dev/null fast 0x3f8"
But it doesn't help, printing to com1 still slow.
However if we print under linux is faster.
Thank you

You haven't realized that you can't mix
both $_ports and $_com1, you have to have
only either one.
You haven't looked into dosemu log or at a
console to see the error message that dosemu
throws, that there are the port conflicts
with such a settings.
You haven't read the thread I pointed you
to, while all the questions you have, were
discussed there, and the slowness was a
main focus of that thread, and the proper
settings too.
Correct the above errors and try again.

Port Access slow

[Pande Gede S]

I use dosemu-1.2.2-1, I have serial printer with foxpro apllication.
How to speed up printing? I have added $ ports = "device /dev/ttyS0 fast 
ox03f8", but it's still too slow.
Thanks you
