I am having a great deal of difficulty getting the serial ports under GNO to
work properly under the gsh shell.
 
1.  Even with the serial ports echo off I get 2 char. back for each I type on
the terminal display.  Data sent to the terminal from the GS is only singal
chars as it should be.
 
2.  Some simple C programs I'v tried writing just to get a feel for gno are
doing some funny things.  Mainly, when these programs are executed on another
terminal (other than the GS), the programs will only dump text out to the
terminals when another program ie-ls or ps, is dumping output to the GS screen.
When the program on "the GS" stops, so do the programs runing on the terminals.
 
Any ideas??

  Use the command "stty -echo" to stop this from happening.

  Make sure you're using the GNO-specific serial devices ".ttya" and ".ttyb".
Using the GS/OS generated serial drivers does in fact result in the behavior
you mentioned.

  I forgot to mention that .ttya is the modem port and .ttyb the printer
port by default- you can change these if you like. In fact, you can change
the device names too.  See the manual and the 'Release.Notes' file for more 
details
