No Startup Program; Serial Communication Test - Intermec EasyCoder 501XP Programmer's Reference Manual

Chapter 2 — Getting Started

2.5 No Startup Program

If the printer starts up in the immediate mode of Intermec Finger-
print (because you have already selected the Fingerprint application in
Intermec Shell, or because the printer for some reason is not fi tted with
any startup program at all), the display window should show the follow-
ing message directly after power-up:
Fingerprint
7.80
To use the Intermec Direct Protocol, you will have to send an
instruction to the printer as described in Chapter 3.2.
2.6 Serial Communications Test
Check that you have a working two-way serial communication by send-
ing a simple instruction from the host to the printer. On the host, type:
? VERSION$ ↵
Provided you have a serial two-way communication, the printer should
respond by immediately returning the version of the installed Intermec
Fingerprint software to the screen of the host:
Fingerprint 7.50
Ok
This indicates that the communication is working both ways.
If the communication does not work, switch off the printer and check
the connection cable. Also check if the communication setup in the host
corresponds to the printer's setup and if the connection is made between
the correct ports. Then try the communication test again.
Once you know that the communication is working, you may proceed
by sending a line of text to make sure that characters transmitted from
the terminal are interpreted as expected by the printer's fi rmware:
FT "Swiss 721 BT" ↵
PT "ABCDEFGHIJKLM" ↵
