When you select the Kermit protocol, all of the Host port fields in the Commu-
nications menu (except baud rate) change to predefined values required by the
Kermit protocol (see Figure 3–26). These fields return to their previously values
when you reselect the DAS 9200 PCL protocol. Before transferring files, set the
Host port baud rate to match the baud rate of your host computer.
NOTE . Data transfers to and from the system may be unreliable at rates above
2400 baud when using the DAS 9200 PCL, or above 9600 baud when using the
Kermit file transfer protocol. You must use either XON/XOFF or DTR/CTS flow
control with the PCL. Flow control is inherent in the Kermit protocol; no
additional flow control is necessary.
In addition to changes in the Communications menu fields, a directory appears
that contains a list of the files of the type selected in the File Type field. The
directory listing shows the file names, file sizes (in kilobytes), and the date the
files were created. The File Name field is a fill-in field; the contents change as
you move the directory cursor with the joydisk or scroll keys.
NOTE
. Some versions of Kermit (for example, UNIX Kermit, but not PC Kermit)
distinguish between ASCII and binary files. If your host Kermit makes this
distinction, remember to enter the SET (MODE) ASCII or SET (MODE) IMAGE
command on the host before starting the file transfer. If you fail to do so, the
data may be transferred incorrectly.
ASCII files include Disasm Format, Symbol Table and some Print Output.
To begin the file transfer (send or receive), enter the necessary information and
select function key F8: SEND FILE (or RECV FILE). A window appears that lets
you track the status of the file transfer. The status window contains informational
fields describing the file name, the data currently being transferred, the number of
bytes currently transferred, and the number of retries attempted during the transfer.
You can abort the file transfer at any time by pressing the Escape key. To force the
last packet of data to be retransmitted, press the Return key.
Reference memories, comparison masks, and trigger libraries are sent and
received as a UNIX V7 tar archive. When you select function key F8: SEND
FILE, the system displays a Building Archive message at the top of the screen.
You must wait until the status line changes to Sending File before starting the host
Kermit. This may take several minutes, depending on the size of the file to send. If
you do not wait, the host Kermit may time out before the system sends the file.
