In some applications, CRC, Checksum, or other trailers follow the end-of-sequence character. In these cases, this option helps to adapt frame transmission to the frame boundary.

If bit 4 is set, VMSE interprets the Sendchars as a 2-byte sequence; if reset, they will be interpreted independently.

If bit 5 is not set, any other characters already in the serial buffer will be included in the transmission after a “transmit” condition is found. If the bit is set, the VMSE will immediately send after recognizing the transmit condition (sendchar or timeout).

NOTE: A transmission might occur if status information has to be exchanged or an acknowledgement has to be sent.

Send Characters

Up to two characters can be entered in hexadecimal representation in the parameter “sendchar.” If a character received on the serial line matches one of these characters, it is immediately sent together with any awaiting characters to the TCP connection. This is specially useful to minimize the response time for specific protocol characters on the serial line (i.e. ETX, EOT etc.). Setting the first Sendchar to “00” disables the recognition of

the characters.

Alternatively, the two characters can be interpreted as a sequence (see “Pack Control” section).

Telnet Terminal Type

This parameter appears only if the terminal type option is enabled by setting

bit 6 in the disconnect mode. If set, the terminal name can be used for the Telnet terminal type. Only one name can be entered.

If the terminal type option is enabled, VMSE also reacts to the EOR (end of record) and binary options, which can be used for applications like terminal emulation to IBM hosts.
