equipment that can transmit and/or receive data using RS232 interface when a port is not receiving data from the device connected to it

a terminal emulation program- computer program that communicates via RS232 interface (i.e. HyperTerminal)

Serial terminal device or CPU terminal program that emulates a serial terminal

time period of inactivity after which a port will be disconnected (the inter-port connection will be broken) serial device or port receiver and transmitter speed; measured in "bps" (bits per second)

a method to temporarily stop and restart serial data transfer (flow). It can be

-Hardware (out-band)- usually using the RTS and CTS physical handshaking signals;

-Software (in-band)- using special characters, usually named Xon and Xoff, inserted in data being transferred;

-Both

1or 3 char sequence inserted in the serial data flow, to disconnect the user from the attached serial device and to return to the initial user menu.

"Carriage Return" character, ASCII code 13 "Line Feed" character, ASCII code 10 "Form Feed" character, ASCII code 09

(i.e. [ Shift ] + [ < ] ) press the keys simultaneously (i.e. [ P ] - [ 0 ] ) press the P and 0 keys consecutively
