You also need to open the fifo in read mode before you tell diald to open
the fifo in write mode. In order to do this you swap the lines starting
with 'fifoCmd' and 'set monfd'. Furthermore, set the open mode to 'r+'
aka O_RDWR which will prevent the open from suspending waiting for the
writer.
set monfd [open $monfifo r+]
fifoCmd "monitor $monfifo"
