Using the PCBridge Software
Appendix D
D-11
Use the following table to identify PCBridge problems and apply
the solution.
Problem Solution
The PCBridge software hangs during initialization;
or the PCBridge software starts, but then the screen
fills with multiĆcolored junk or menus do not
disappear when they should.
There is not enough memory to execute the PCBridge software. Generally, the PCBridge
software reports that it may not have enough memory to execute before it fails.
The PCBridge software appears to execute
correctly, but nothing seems to be sent out on the
serial port.
Make sure that the serial cable is plugged into a serial port on your programming terminal and
into the OSĆ9 system.
Ensure that the serial port is properly installed. If the serial port is located on an addĆin board,
you may need to set switches or jumpers to activate the serial port correctly and to prevent
conflicts with other serial port(s) that may be present in your system.
File transfers never begin. Abort the transfer on the PCBridge software's end by pressing
[Ctrl-F]
. Wait a few
seconds. If that does not seem to stop the transfer, try pressing
[Ctrl-K]
. Check the
communications parameters.
File transfer aborts. Ensure that the file type is specified correctly. It is common for a PCĆDOS file to contain an
extended ASCII character (one whose numeric value is greater than 127). Such characters are
commonly used for drawing lines or boxes. While these characters are considered legal text,
they are not legal in OSĆ9.
Ensure that you have enough disk space on the PC to receive a file and enough OSĆ9 disk
space when sending.
Many characters dropped in screen display. You may find that some characters are correctly displayed, but many are simply dropped from
the display and do not appear at all. Possible reasons include:
• You are running a program which conflicts with the PCBridge software in some way. Try
running the PCBridge software by itself.
• You are running at too high a baud rate for your programming terminal to keep up with the
remote system. Try using a lower baud rate.
• The serial port or cable is damaged. Try replacing the cable, then try another serial port if
there is one.
In addition to the main PCBridge program and the cross C compiler
system, the PCBridge software includes several utilities:
Name Description
binex Binary to SĆrecord converter
cudo Convert text file EOL characters to UNIX, DOS, or OSĆ9
exbin SĆrecord to binary converter
fixmod Modifies module CRC and parity
ident Module identification utility
merge Merge multiple files to a single file
names List names to stdout
os9cmp File comparison utility
os9dump File dump utility
These utilities are not directly available from the PCBridge menu; you can
invoke them from the PC-DOS command line.
