Manual Entry of a Command
TAP Protocol Timing Issues
The OSMAC Base Station will only wait for 15 seconds for a response to return from the entry device. If a response is
not received within the time-out period, the base station will cancel the current transaction. It will send the <ESC>
<EOT> <CR> sequence.
TAP Protocol Line Feed Issues
The OSMAC Base Station will ignore all <LF> characters it receives. The entry device may send a <LF> with any <CR>.
XOFF
In the very unlikely event that the user enters more commands than the OSMAC Base Station can queue up, the base
station will send the <XOFF> character before sending a carriage return. The base station will send the <XON> charac-
ter when buffer space is available for more commands. If the base station does not receive any data within 10 seconds
after sending an <XON>, it will send another <XON>.
EOT
Whenever the OSMAC Base Station terminates a session by sending the <EOT><CR> sequence, it will drop the DTR
signal on the RS-232 signal for 250mS. This will normally cause any linked modem to disconnect.
Sending Multiple-Line Commands
Users cannot send the <CR> return character into the serial port. Instead of a <CR>, use the TAB character if you wish
the command to continue on another line of a multi-line satellite. The OSMAC Base Station will translate the TAB char-
acter to a <CR> when it transmits the command to the satellite.

Comment
The entry device tells the OSMAC base station that it wants
to manually send a POCSAG command by ending the M.
The Osmac Base Station will respond within one second of
the M sequence signifying that the entry device has success-
fully logged on to the base station, and it is ready to receive
command information. The base station begins by responding
with this prompt.
The user responds with the satellite number he/she wishes to
transmit commands to.
The base station responds with one of the following mes-
sages, depending upon the type of satellite controller that the
satellite number is assigned to.
The user enters the command to send to the satellite.
The base station displays this command as it sends the it to
the satellite.
One of these messages will then be sent from the base sta-
tion depending upon the current situation of the command
that was entered. The serial port has a 45 second activity
time, and it will force and end the manual session if the user
does not complete the command in that time frame.
