[RTTY] USB Signal Link

[Nick Smith]

I am helping a person new to RTTY and writelog and has a USB Signal Link device but can’t get to work on writelog.  It works on ham radio deluxe and he says that it works on MMTTY.

Anyone know anything about this device and how to get to work on writelog?  

He doesn’t have and comports so a recommendation of a working USB to serial would also be appreciated.

Thanks to all in advance.
