.SH SYNOPSIS
.B "bind -b '#t' /dev"

.B auxi/rdbgsrv

.SH DESCRIPTION
.I Rdbgsrv
interposes itself between
.I dev
(default:
.BR /dev/eia0 )
and
.I mountpoint
to convey 9P messages via the serial port to and from a 9P server program
running on a board running native Inferno.
The
.B \-f
option specifies the serial device; the default is
.BR /dev/eia0 .
The
.B \-s
option sets the line speed; the default is 38400 baud.
The
.B \-d
option selects debugging options by a bit mask:
1, print trace of 9P message types;
2, print actual 9P message contents.
.PP
The monitor program on the board must be started first.
.I Rdbgsrv
writes the two byte message
.BR go ,
and keeps reading the device until it sees the reply
.BR ok .
It then attempts to mount the exported name space, and
copies 9P messages to and from the device.
.PP
Once
.I rdbgsrv
is running, any device files provided by the program
will be visible at
.IR mountpoint .
