TI-PRO KERMIT version 2.28 revision 5 emulates a H19 terminal (VT52 mode).

How to use KERMIT with an TI internal 300-baud modem

Make sure you have KERMIT.EXE and COMMAND.COM on your A: floppy.
Enter "KERMIT" to start the program.  Then tell KERMIT that you want
to use the modem, which is in port 3, at 300 baud.  Use the CONNECT
command to start talking to the modem.

To do auto-dialing, type in the letter capital "T", then the phone number,
and end with a capital "X".  The letters you type in will not be echoed.
Do not hit the RETURN key.  The modem will type "E", the phone number, and
then "F".  It will type "R" when the phone starts ringing at the computer.
Wait a few seconds, then hit the RETURN key 2 or 3 times.
