CHAPTER 5: ASYNCHRONOUS DCE CONFIGURATION
Viewing an Option Profile
To display the option values for any profile, use the view command. Type view to display the
values of the active profile. Type view p1 to display the values of stored profile p1. Replace p1 with
p2 or p0 in the view command to display their values.
Remember that you can display the options on your data terminal screen and change them
whenever you are in local mode (that is, not transmitting data). To suspend data mode and
enter local mode, rapidly type the Attention sequence: +++. The system will display the
[ CMD: ] prompt.
Viewing Individual Option Values Within the Active Profile, pA
You can also use the view command to check the value of an option within the active profile. For
example, to check the value of Parity, type view parity. Both the current and possible values will be
displayed on your data screen, for example:
[ current value
= even ]
[ p o s s i b l e v a l u e s = e v e n
Typical Data Option Settings for Data Transfer
This section describes which options you will need to modify for three types of data transfer.
Character by Character Transmission
For typical character by character data transmission, activate the factory profile (p0). Depending
upon the network's configuration, it may be necessary to change the Mode option to DX25. (Check with
your system administrator for your system's configuration.)
Line/Block at a Time Transmission
You may want to either create or change a line or block of characters at a time before sending them
to the far-end. (This feature is only applicable to X.25 or Mode 3 data connections; see Mode in
CHAPTER 4: DEFINITIONS OF 7500 OPTIONS.)
First, activate the factory profile, p0. Second, set the Mode option to DX or BA. Third, set the Edit
option to on. Fourth, change the Forwarding option from off to the desired value; typically this should
be cr. Make sure that the 7500's Echo option is set to on and the data terminal's echo option is set to
off.
Binary (8-bit) File Transfer
Use the following recommended setting if you are transferring a binary (8-bit) data file between
computers.
Activate the factory profile (p0). Set flow control (Rec.flow and Trans.flow) to either off or eia.
Both endpoints must (1) either be operating at the same speed or (2) both support eia flow
control.
