FSL Setup via PC's Parallel Port
Xerox FS 3270, User's Guide
8.FSL Setup via Xerox FS 3270 Serial or Parallel Port
FSL support on the serial or parallel input port is defined by temporary escape character, FSL Y100 and ESC X1.
The Engineering Function Y249 (FSL setup via share port) allows you to program the FSL parameters for coax input directly via the serial or parallel input port.
When FSL programming is preceded by FSL Y249, the Xerox FS 3270 will interpret the FSL as sent via the coax line.
Example:
&&??%%Y100,10,’SHARESTRING’%%X1
Sent to the serial or parallel input port, this command string will program FSL Y100 on the serial or parallel input port it was sent to.
&&??%%Y249,PASSWORD%%Y100,10,’SHARESTRING’%%X1
Sent to the serial or parallel input port, this command string will program FSL Y100 on the coax port.
In the description below, it is assumed that you know how to define an escape character (this must be done before you can use the Y249 function).
Character conversion
When the engineering function is received, all the following characters in the Xerox FS 3270 are converted to LU3 characters.
The characters are now interpreted as received by the coax line.
This functionality is automatically deactivated after timeout on the share port used.
NOTE:
To ensure correct conversion of the characters following the engineering function, use characters existing in the symbol set
