Kermit pc file transfer
...g the cable during a transfer. • Explain how the program Kermit knows the name of the file being transferred. Actions taken: 1) Both Pc’s serial ports were connected to a breakout box (bob) with serial cables. 9-25 pin adapters (gender benders) were needed for the connection from the bob to the serial ports of each PC (which is found on the rear of each computer). 2) The Kermit program was executed on the two PCs, and was set in connect mode. The settings on the bob were altered until the keystroke from one PC was displayed on the monitor of the other (and visa-versa). It was clear from altering the settings on the bob, that the minimum amount of connections that will achieve connectivity is two, send(2) and receive(3). The LED display on the bob displayed which lines were on or off with a red light. We tested the connection by typing the c command at the prompt, which allowed us to enter text on one pc, and display the characters on the others monitor (7 bits passed per character, 1 bit used as the stop bit). Example of how text appears on the other computer’s monitor 3) Kermit was then set in command mode. The “set speed” command was used to distinguish the result of PCs running at different speeds (i.e. SET SPEED 9600). We set the parity of both PCs to even. 4) File transfer was achieved by using the SEND and RECEIVE commands in command mode. Once one computer was in receive mode, the other could transfer files using the SEND command (i.e. SEND C:myfile.txt). There was a timer on the send and receive modes. 5) We noticed while transferring large files (we used MSWORD file) at the highest speed setting (9600) that the bigger the file the slower the transfer went. While transferring a file the actual transfer time it takes differs from the transfer time calculated from the file size. While sending the file, the actual time calculated was 3 minutes, and the transfer time calculated from file size divided by transfer rate (675,000 / 9600kb) was 1minute and 10 seconds. 6) Momentarily disconnecting the cable during the transferring of a file results in the typed information being lost on the other compu...
