vSPC input length restriction?

We're using a variant of the virtual serial port concentrator with ESX 5. We've noticed that when a VMs console is connected through vSPC, input is

truncated to 384 characters. This doesn't happen if we create a VM with a telnet console port and telnet in. We've verified that the packet sent from

vSPC to the host contains the whole line.

Is there a limitation on vSPC input sizes, or some setting that we need to change?

Hi

Welcome to communities.

I assume due to data transfer speed only

No, it seems to just truncate. This is repropduced with manually cutting and pasting into the terminal window for the console.

In a related update, we have been able to work around this by modifying the send code in vSPC to send a maximum of 300 characters and

then do a short sleep.
