[TimeWave-AEA] PK232MBX Loop back test question

[Scott Hill]

Hello, I am looking for some ideas for a PK232MBX problem.

I bought a used PK232MBX (v. 7.1) with a good set of documentation and 
cables.  I set the PK232 up for the loopback test as described in the 
manual.  I am using HyperTerminal for the communications program.  I 
am set up at 1200 7-E-1 as shown in the manual, and I have good 
communications between the computer and the terminal.

When I power up the PK232 I get the greeting message screen:  
Copyright, Release, Version, etc, and cmd:  So far so good.

Now I am supposed to type in a series of commands to perform the loop 
back test.  The first one is:  MY AAA <enter>.  That goes OK and I get
the proper reply.

Then I type C AAA <enter> and there is no response.  If, however, I
type <CONTROL-C> I then get the correct response.  The same is true 
for all the other tests.  They operate correctly, but I only get a 
response after sending <CONTROL-C>.

It is as if once I am connected I don't get anything from the PK232
until I go back into the command mode--actually looks like a buffer
problem or something.
