What does it do, exactly?

I can use screen /dev/remserial1 and that works fine. I think I need to specify the baud rate and comm settings of the virtual device.
Sounds like setting the baud rate is what these serial programs are failing on... it's not acting like a serial port, it's acting like a virtual terminal. A terminal emulator that insists on a real serial port might never accept it.

That's a very odd way to create a device file... Have you tried not doing this and just letting remserial create the device itself?

NAME
cyclades-devices - tables for driving cyclades-serial-client DESCRIPTION
The cyclades-devices file supplies all mapping between Unix device files (/dev/*) and the addresses of serial ports of Cyclades Terminal Servers. It contains one entry for each serial port, with the following format: device:rastype:rasname:physport:type:options Note: A # character at beginning of line indicates a comment The entry fields are: devname - A full pathname of the file that will be associated to the serial port. It must start with a "/dev/" preffix. Two naming schemes may be used here: - devname does not exist, and will be linked to a free pseudo-tty. This is the default behavior of cyclades-ser- cli. - devname is the name of a valid slave pseudo-tty. In this case, the '-t 1' option must be assigned in options field. (Note: this option is not supported by this release). rastype - Terminal Server type: - prts, for Cyclades Pr302X/TS Terminal Servers. - path, for Cyclades PathRAS Terminal Server. rasname - Host Name or IP Address of the Terminal Server where the serial port resides. physport - Number of physical port in the Terminal Server. If treated as the IP address associated with this port, in a IP-based addressing scheme. type - Server type that will be contacted to handle the serial port: - rtelnet, for Remote Telnet Server - socket, for Socket Server options - Per-port specific options, passed to cyclades-ser-cli program. EXAMPLES
1. Device on a PR3020/TS Terminal Server pr3k Port 1, accessed through /dev/ctty01 device file name, using telnet protocol (remote telnet server) /dev/ctty01:prts:pr3k:1:rtelnet: 2. The same device, but with an IP address pr3k_port1 associated to the serial port (IP-based port addressing) /dev/ctty01:prts:pr3k_port1:0:rtelnet: 3. Device on a PathRAS Terminal Server pr3k Port 2, accessed through /dev/ctty02 device file name, using socket protocol (socket server) /dev/ctty02:path:pr3k:2:socket: FILES
