VT220

SP> Hello. I am playing with one VT220 plugged to the serial port of SP> one Pentium 4 laptop. I have Cygwin installed, with Init and SP> getty started, and the serial port defined with VT200 and 9600 SP> bauds, and I want to open one session under Cygwin from the SP> VT220. Of course something happens under Cygwin, because every SP> "enter" opens a new login in the ps list under Cygwin. But SP> nothing appears in the VT220 screen... SP> With this previous explain, the question for gurus is: Would I SP> need one DEC cable to plug the VT220 (by the way, 25 pin SP> interface) in the Laptop Serial `port (9 pin port) ? Or can I use SP> a normal serial cable ? A plain old 25 to 9 Null Modem cable should work. It sounds like you have that, because you see something happening at the host end. There may be a flow control mismatch. If your PC serial port is set up to use RTS/CTS flow control, that would account for no output showing up. I forgot if the VT220 supports that flavor of flow control. Look through the Setup. If not, change the PC settings to "no flow control" (or better yet, XON/XOFF, if that's available). paul
