PDT 1100 Terminal DLL Guide

To handle CR-LF codes as data, specify the +C option. CR-LF codes in records are

transmitted as data:

When downloaded:

Even if you specify the +C option, use CR-LF codes as a record separator. If a record’s length

is more or less than the specified record length in a file, an error (error code 76) occurs and

the transmission is aborted. For the +C option, refer to Options on page 2-7.

To download data files containing CR-LF codes in records to the PDT 1100:

1. At the host computer, specify the +C option in Ir-Transfer Utility C DLL

2. At the PDT 1100, set the [Data] on the space code handling screen in System Mode

(or in PDT 1100-BASIC 3.0, specify the T option to “protocolspec” in the XFILE

statement) to regard space codes in the tail of a data field as data.

If [Ignore] is selected (or no T option is specified), the PDT 1100 ignores space code s in the

tail of a data fi eld and data is not transfe rred correctly.

For [Data] setting, refer to the PDT 1100 Product Reference Guide. For T option setting in

the XFILE statement, refer to the PDT 1100 Programmer’s Guide.
