I am having DTC problems.  I have a barcode printer that will print
fine from a DTC.  However, the printer can send back status
information (out of labels, busy etc.)  But I cannot get the DTC to
see the status string.  When I connect an HP 700/92 terminal to the
printer, I can get the status string no problem.  The printer seems to
be using some hardware handshaking.  I connect the printer to a modem
port on a DTC48.  When I try to enable hardware handshaking in NMMGR,
the validate says something like "HANDSHAKING FOR MODEM PORTS NOT
SUPPORTED FOR DTC48" and the validation fails.   I assume the problem
is with the DTC48 as handshaking on direct ports is absurd.
 
In order to get the status string, I send a cntrl-A and I should
receive an eight byte string.  My Fortran program just keeps timing
out on the terminal reads.  If I connect the terminal immediately
after this timeout, all the status strings come flying onto the
screen.
 
HP support says this is a custom job and I will have to pay a
consultant to attach an unsupported device.  I just need to know how I
can make a DTC48 modem port act like an HP700/92 terminal.  I may be
getting a different terminal server and skip the DTC altogether like
many others have.  Any help is greatly appreciated.
