Note that there are also 

virtual

 serial ports which service RUDICS Internet 

Communications. They appear as net/<0>. This section does 

not

 apply to the virtual 

serial ports. See section 12, Internet Communication: Iridium RUDICS.

Devices behave differently in the areas of character transmission and Carrier Detect 
support.  Although the glider can transmit characters at 115,200 baud, it suffers from 
“buffer overrun” when receiving characters at this rate.  In the context of servicing all its 
tasks, the glider’s main persistor simply can not consume the characters in the 
hardware receive buffer fast enough.  Thus, the glider appears to drop received 
characters at 115,200 baud.

For freewave devices, Dock Server solves this overrun issue by verifying that each 
character sent to the glider is echoed by the glider.  Once Dock Server receives a 
character’s echo, it sends the next character and waits to receive its echo.  Simply 
adding a delay between sending characters does not work since the communicating 
freewaves have their own character buffers and transmission timing.  For direct devices, 
Dock Server uses the inter­character delay approach to solve this overrun issue.  For 
modem (Iridium) devices, this issue does not occur due to the inherent low baud rates.

Typically, Dock Server monitors the Carrier Detect (CD) line to determine when a glider 
is initiating and terminating communication.  When the CD line transitions low to high, 
Dock Server assumes a glider is initiating communication and notifies all Glider 
Terminals accordingly.  When the CD line transitions high to low, Dock Server assumes 
a glider is terminating communication and again notifies all Glider Terminals.  This 
approach to determining glider to Dock Server communication status works for modem 
and freewave devices since they support CD.  However, since direct devices do not 
support CD, Dock Server treats gliders connected by a direct device as always in 
communication with the Dock Server.  That is, in Glider Terminal, the icon next to such 
a glider is never red – regardless of whether or not a glider simulator is actually 
attached.

11.4 How Does Dock Server Recognize a Glider

Dock Server performs many functions that depend on knowing a glider’s name.  Among 
these functions are notifying Glider Terminals when a specific glider has connected and 
disconnected and sending glider status emails to that glider’s subscribers.
