I hav a Digi Neo 8 port serial card installed in an HP Proliant ML310, running SCO Openserver 5.07 . Attached to the serial ports are 3 different laboratory instruments . My problem is the following : when sending data to the instruments via the serial port, the instrument only receives the first 56 bytes, rest is discarded. In recieving data from the instruments ther is no limit in the number of recieved bytes. Ports work properly when a teminal is attached to them.
A "cat" of a file to the port shows the same problem : only the first 56 bytes are transmitted.
I've contacted Digi internaitional support, they claim it's a flow control issue.
Anyone out there who has had or heard of such a problem before ?
