The RcvSeqNumbers parameter determines whether a computer receives sequence numbers from 
the host. When the host is sending sequence numbers, this flag must be set to Yes. When the host 
is not sending sequence numbers, this flag must be set to No. 

When the parameter is set to Yes: 

•  The computer uses the first character of text in a host-to-terminal message as a 

sequence number. The character does not appear on the display, nor is it sent to the 
optional RS-232 port. 

•  If the next message has the same character in the first position of text, the message is 

acknowledged by the computer but otherwise ignored. 

Valid options:  

Yes, No 

Default setting: 

No 

Parameter may only be modified by a user with an access level of 2 or 3. 

The AltAckMode parameter determines whether the compose buffer is cleared upon transmit. 

•  When the computer transmits a message (and the network device acknowledges it), 

the compose buffer is left in a “cleared-to-header” state (or, in the transmission of a 
form message, a “cleared-to-protected-characters-only” state) and the computer is 
ready to transmit again. This condition is known as the Auto Refresh mode. 

•  This setting is equivalent to sending Expanded Function J from the host to the 

computer. Refer to Chapter 5, “Expanded Functions”. 

•  When the computer transmits a message (and the network device acknowledges it), 

the message sent by the operator remains in the compose buffer. 

•  This setting is equivalent to sending Expanded Function I from the host to the 

computer. Refer to Chapter 5, “Expanded Functions”. 

Valid options:  

Yes, No 

Default setting: 

No
