| Host | Terminal | Connection | Host type name |
|---|---|---|---|
| Unisys ClearPath MCP (A Series) | T27 (the TD 830 family) | Telnet, port 23 | t27 |
| Unisys ClearPath OS 2200 | UTS 60 | Telnet, port 23 | uts |

| Airline reservation hosts | ALC agent set | MATIP type A (RFC 2351), port 350 | alc |
Try a sample host
Download the compatibility lab to run five synthetic host applications on your computer. Its readme gives the exact connection commands, transactions and expected results. Python 3 and WND Terminal are required. These examples give you a working start; during a proof of value, we test your own application workflows and address any compatibility differences.
Additional model profiles
The current desktop release also has scoped starting profiles for Wyse WY-50, WY-50+ and WY-60, the IBM 3151 ASCII Display Station and HP 700/94. For older UNIX and PC services, see the VT52, VT102, partial VT420, partial VT520, BBS ANSI/CP437, SCO ANSI and partial AT386 pages. Each page gives the tested connection, sample transaction and present limits. The sixteen-host software lab lets you open a visible screen before connecting to your own hardware.
Connect
On the connect page, open Unisys, HP, Tandem and airline hosts, pick the host and type its address. The port starts at the usual one. A few settings depend on the terminal.
- Terminal type, for all but ALC. Leave it empty for WND Terminal’s default (
TD830,UTS60,HP700/92,T6530), or type the one your host expects. - T27 can send only the fields up to the cursor in forms mode.
- UTS 60 can have XMIT send the open fields, everything, or only the fields you changed.
- HP can start in block mode. The host can switch either way.
- 6530 can send each character as it’s typed. Normally a line is typed on the screen and RETURN sends it, as Guardian and TACL expect.
- ALC takes the agent set’s address from your airline’s network team (five hex bytes such as
00 00 01 0A 41), and ASCII or EBCDIC characters.
TLS on a secure port works for the Telnet hosts as for any other connection. From the command line, use --connect "Name=t27:host:23", and likewise uts:, hp:, 6530: and alc:.
Keys and status
Under the screen, these sessions show the terminal’s own status words, such as T27 FORM and XMIT, UTS MSGW, HP BLOCK and 6530 CONV, the host’s message line where the terminal has one, and a row of the terminal’s keys to click.
On a small screen, swipe the table to read all columns.
| Terminal | Enter | Function keys | Other keys |
|---|---|---|---|
| T27 | XMIT | SPCFY on the keypad. Clear clears the page or the open fields. | |
| UTS 60 | XMIT | F1 to F22 | SOE and MSG WAIT on the keypad |
| HP 700/92 | ENTER in block mode, RETURN in character mode | f1 to f8, labelled as the host defines them | |
| 6530 | RETURN | F1 to F16 and SF1 to SF16 | NEXT PAGE, PREV PAGE, ROLL UP, ROLL DOWN, INS LINE and DEL LINE |
| ALC | Transmit | SOM and Reenter on the keypad |
In block and forms mode, typing goes only into the open fields and digits-only fields refuse letters. Macros, the automation API, Fill from Excel, recordings and Send to help desk read these screens as they read 3270 ones, and macros press these keys by name, such as press XMIT or press SF1. Password fields are never shown, read or recorded.
IT settings
List these hosts in the policy’s Connections with HostType "T27", "UTS", "HP", "6530" or "ALC", or |t27, |uts, |hp, |6530 and |alc on a connection line. With LockHostType on, the connect page doesn’t offer them and only IT’s own connections of these types open.
What isn’t covered
- T27 supports configured F/SF key bytes and page memory. Automatic host-programmed key definitions and full forms framing still need a customer-host check.
- UTS over ISO transport (RFC 1006) still needs the host application envelope. Expanded color FCC behavior and auxiliary devices need a customer-host check.
- HP 2392A identity and common status requests are answered. HP 700/94-specific queries, edited and transmit-only fields, and full VPLUS forms remain outside the current subset.
- The 6530 now answers terminal status and keeps independent selected and displayed pages. Block LRC/ACK retry variants still need a customer-host check.
- ALC hosts that need IPARS or padded Baudot coding. ASCII and EBCDIC work.
- Data General and Siemens terminal modes. Scoped Wyse and ANSI profiles are listed separately on the supported-systems page.
- IND$FILE, which is for mainframes only.
