.SH DESCRIPTION
38 
.I Drawterm
39 
is
40 
.I not
41 
a Plan 9 program.
42 
It is a program that users of non-Plan 9 systems can use
43 
to establish graphical
44 
.IR cpu (1)
45 
connections with Plan 9 CPU servers.
46 
Just as a real Plan 9 terminal does,
47 
.I drawterm
48 
serves its local name space
49 
as well as some devices (the keyboard, mouse, and screen)
50 
to a remote CPU server, which mounts this name space
51 
on
52 
.B /mnt/term
53 
and starts a shell.
54 
Typically, either explicitly or via the profile, one uses the shell
55 
to start
56 
.IR rio (1).
57 
.PP
58 
By default,
59 
drawterm
60 
uses the CPU server
61 
.B $cpu
62 
or
63 
.BR cpu .
64 
and the authentication server
65 
.B $auth
66 
or
67 
.BR auth .
68 
The
69 
.BR -a ,
70 
.BR -c ,
71 
and
72 
.B -s
73 
options specify alternate authentication, CPU and
74 
.I secstore
75 
servers,
76 
respectively.
77 
(Edit the source to set appropriate local defaults.)
78 
.PP
79 
.I Cmd
80 
is a command to be executed remotely.
81 
Options
82 
.LR e ,
83 
.LR k ,
84 
and
85 
.L u
86 
have the same meaning as in
87 
.IR cpu (1).
88

89 
Drawterm has been ported to
90 
FreeBSD,
91 
Irix,
92 
Linux,
93 
NetBSD,
94 
and
95 
Windows.

.SH DIAGNOSTICS
101 
Drawterm prints most diagnostics in its own window.

104 
.IR rio (1)
105 
.SH BUGS
106 
Although at first
107 
.I drawterm
108 
may seem like a Plan 9 terminal, in fact it is just a way to provide a CPU server
109 
with some terminal devices.
110 
The difference is important because one cannot run terminal-resident programs
111 
when using
112 
.IR drawterm .
113 
The illusion can be improved by delicate adjustments in
114 
.BR /usr/$user/lib/profile .
115 
.PP
116 
It would be nice to be able to change the default servers
117 
without recompiling.
