address information. If necessary, you can set the TSAP addresses individually.

Connections
TSAP Format
ISO-on-TCP connections have a TSAP length of 1 to 16 bytes. When you are
entering values, the current length is displayed automatically (visible display: 20
ASCII characters). Local and remote TSAPs can be input as hexadecimal values
or as ASCII strings. If you make your entries in ASCII, the characters you enter are
also displayed in hexadecimal format. If you make your entries in hexadecimal,
printable characters are displayed in ASCII (8 hexadecimal values are visible). If
you enter nonprintable characters, the ASCII display is gray (no further ASCII
entries possible) and the nonprintable characters are displayed as periods.
Local and Remote TSAPs
Remote and local TSAPs can be identical since the connection is uniquely
identified by the different MAC addresses. If you require more than one connection
between two stations, the TSAPs must also be different.
