Dear Sergej, Thank you for the inquiry. Could you please help us to clarify your issue? Do you mean you can use the "Telnet COM Port Control Option (RFC2217)" to send the DTR signal with CSE-H25, but it did not work with CSE-H20? First, we suggest you follow this checklist to troubleshoot your issue: https://www.eztcp.com/en/support/view?page=1&cid=286 We also recommend you to check and make sure your CSE-H20 is updated to the latest firmware, v2.0A, and there is no problem with the serial cable, etc. https://www.eztcp.com/en/download/pds-view?bbs_id=15&page=1&cid=272 If the problem still happens, could you please connect your CSE-H20 and CSE-H25 to ezManager, and take the screenshots of the setting parameters for both devices. You can send us the screenshots via email at support@eztcp.com. Thank you for your understanding.

Second function , which I need, is DTR signal. From Host I send to CSE-H20 "DTR active" state. When I use USB/RS232 converter - function work properly. When I use CSE-H25 with telnet - function work properly. When I use CSE-H20, this function didn't work. Thank you, Sergej
