Probable cause
The port number is incorrect.
Inputting to a write-only external device. Check the port and external device
The port is already open. The same
port has been opened twice using the
OPEN command.
An error has been generated while
communicating with an external device.
Not used.
Incorrect port communications
parameters.
If the ON COM interrupt is being used,
the port communications parameters
will not be set to proper values.
When the LOAD command was
executed, a line with no line number
was discovered in the program being
transferred to the ASCII Unit.
An unopened port number has been
used.
Incorrect framing (framing for start bit +
data + parity + stop bit) for received
data read from the port.
Attempted to write to a read-only
external device.
An invalid device symbol has been
used in the OPEN command.
I/O commands such as a PRINT
command may be in conflict with each
other due to an interrupt.
Not used
Note The indicates the port number generating the error.

Corrective measures
Check the port number.
specifications.
Delete one of the OPEN commands.
Check the communications network.
---
Check the communications parameters
for the port or check that the restrictions
on baud rate and communications
interrupt conditions for port 1 and 2
have not been exceeded.
Check the program being transferred to
the ASCII Unit.
Open the port using an appropriate
OPEN command for the device symbol.
Check whether or not the
communications conditions specified
using the OPEN command match the
framing of the external device.
Check whether or not the device
symbol specified using the OPEN
command matches the external device
specifications.
Check the OPEN command device
symbol.
Correct the program so that I/O
commands do not compete.
