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.

mdc
mdc(4) Kernel Interfaces Manual mdc(4)Name
mdc - DS5100 serial line driver
Syntax
device mdc0 at ibus? vector mdcintr
device mdc1 at ibus? vector mdcintr
device mdc2 at ibus? vector mdcintr
Description
A DS5100 base system (mdc0) provides four asynchronous ports. An optional asynchronous card (mdc1 and mdc2 ) can be added to supply eight
additional ports.
The mdc ports are used as follows:
Port Usage Connector
0 Console port 6-pin MMJ on CPU board
1 Local terminal 6-pin MMJ on CPU board
2 Full modem control port 25-pin D-Sub on CPU board
3 Local terminal 6-pin MMJ on CPU board
An optional asynchronous board provides an additional eight lines:
4 Local terminal 6-pin MMJ
5 Local terminal 6-pin MMJ
6 Full modem control port 25-pin D-Sub
7 Local terminal 6-pin MMJ
8 Local terminal 6-pin MMJ
9 Local terminal 6-pin MMJ
10 Local terminal 6-pin MMJ
11 Local terminal 6-pin MMJ
The console baud rate is set to 9600 baud by default. You can change this by setting the baud environment variable from console prompt.
Each communication port from the serial line controller behaves as described in the reference page and can be set to run at any of 16
speeds. For the encoding, see
You can establish the state of port 2 (port 6) by specifying either modem or nomodem as part of the file entry.
Restrictions
The speed default is to 9600 baud on the console port. The console device must be set for 8-bit character length with one stop bit and no
parity. The driver enforces these restrictions; that is, changing speeds with the command may not always work on console ports.
