When you say the printer "stops printer" do you mean it stops printing
altogether, or that it stops feeding the paper and keeps printing over
and over the same line?

Perhaps you need to change the character set options in dosemu.conf?
There are term_char_set for 1.0.2, and for the development versions
internal_char_set and external_char_set.

Hi ryan
 I have saw the charset options in the new technical readme in the
development versions but i have not tested yet because i am having very
trouble with the printer that it´s more important to me, well i take to
5 hours proving options with setserial and stty, i realized wich when i
tried a "cat largefile > /dev/ttyS0" in linux i had the same result, and
the end of the printed page character disorder and not the whole file
printed, i had tested the closing_wait "infinite" like i saw in the
printing howto but it didn´t worked, i found in a old newsgroup a
message that recommends this.
stty -F /dev/ttyS0 opost onlcr tab3 crtscts
setserial /dev/ttyS0 uart 16450
Later than this i can print large files with cat so i was very happy and
i went to probe in dosemu trusted but in dosemu the printer do the same
thing!!!, and it´s exactly the same that linux "cat largefile >
/dev/ttyS0" did before i applied the commands showed above. Do you know
any way to resolve that o how i can give a direct access to dos, i saw
in doc but i don´t understand very well, i need that the dos knows which
is com1, it doesn´t works if i add to the ports list 0x3f8 without say
it that it´s com1.
