M204.1890 Number of write buffer waits - token
This number is the count of write buffer waits in the Model 204 SNA Communications Server (also known as VTAM) interface module (VT75). This value is advanced by one each time Model 204 tries to write to a terminal and a buffer is not immediately available.
System manager response: This number should be monitored. If the number of waits grows or seems excessive, the number of buffers should be increased.
