Groff text output processing issues

Question

I need to format documents with the groff -mm macros and need help on some issues: image showing issues

============
You can see it is putting some blank lines at the top and a page number. I need it to run one continuous column starting at the first line of the file.
It is using ansi escape codes, i need it to strictly use ascii text characters.
I also want no default indentation and the page width needs to be 80 chars wide as i am sending it to a text file not a printer.

You can reformat the page with .PGFORM <line length> <page length> <page offset> <line break>. .PGNH skips the header printing on the first page.

.PGFORM 80 0 0 1
.PGNH
ConImp [-a] [-t] [n<name>] [m<time>] [e<editor>]
 -a = non-ANSI terminal
 -t = use test port
 -n = force user name
 -m = maximum play time
 -e<editor> = allow external editor
-a:
 If your terminal is not ANSI compatible use this to prevent ANSI codes being sent
-t:
 Use the testing port
-n<name>:
 Force the username to this user, used in BBS doors
-m<time>:
 Set maximim play time
-e<editor>:
 Set the external editor, if any. For example to use VI editor

The text above is only guessed ;-)

I guess that the escape characters are added by the tty output device (-T ascii) which is grotty. grotty allows you to disable color and escape sequences by the -c option. This flag should be propergated to grotty if you call groff -c ... .

Edit

with the following call you can switch off the hidden call to grotty with -Z and pipe the output to an explicit call of grotty with the -c flag.

groff -mm -Tascii conimp.mm -Z|grotty -c
