Section 5 - General Configuration and Usage Information

5.1 Protocol Converter 3101 and VT100

- Special Considerations

Converter Quirks

The following list must be considered a small fraction of the total selection of protocol converters. In addition,

due to constant changes and RPQs to converter hardware and software for the same brand/model this quirk list

may not be valid. Expect the worst.

IBM Series 1 (Yale ASCII Package)

-uses backspace (08 hex) as ENTER key

-no flow control (no XON/XOFF)

-loses data when overrun (CFXPROX auto-resend AID sometimes corrects)

IBM 7171

-channel attached (sends data to screen out of sequence) (may need DIALOG LINEDROP

to disconnect)

-uses backspace (08 hex) as ENTER key

-no flow control on some models (no XON/XOFF)

-loses data when overrun (CFXPROX auto-resend AID sometimes corrects)

(ROM chip update is available from IBM that allows 1500 byte blocks as of 01/88)

-if bytes are being dropped, try using KEYDELAY set to 50 millisecs

IBM 7626

-SNA only. Little box, a poor 4 line converter

-uses backspace (08 hex) as ENTER key

-no flow control (no XON/XOFF)

-loses data when overrun (CFXPROX auto-resend AID sometimes corrects)

IBM 3708

-should be configured with “medium” size buffer

-flow control is optional (not needed with medium/large size buffer). The 3708 should be

configured to

not

send XOFF/XON pairs as punctuation of the data stream

-BEL issued for line errors (locks keyboard till RESET). If the 3708 is in file-transfer mode, this

lock will not happen. Esc > to enter file-transfer mode and Esc < to turn it off

IBM 3174 with Async Adapter (up 32 lines)

-cannot configure buffer size

-has XON/XOFF flow control

-we have tested up to 19.2

-cannot upload effectively. Due to small input buffer size data transfer upload forces many

many XOFFs
